For Anxiety and Sleep
Size: 30 Count (Pack of 1)
Definitely recommend, a family members psychiatrist prescribed it vs big pharma medication as it's been proven to work as well as many anxiety meds without the side effects, it helped with the anxiety that my family member was diagnosed with, take before bed to calm the mind and for better sleep, and take it consistently

they're decent supplements
Size: 30 Count (Pack of 1)
my psychiatrist recommended these to me to help with my stress & anxiety induced insomnia but so far they don't really help a whole lot aside from making me a bit sleepy. it wore off pretty quickly the first few nights but overall i'd say they're pretty decent, just a bit on the spendy side to be getting regularly. they do cause some burping, though i expected that much going off of the reviews and it was only the first night i tried them.

A Powerful Anxiolytic and Sleep-Enhancer
Size: 30 Count (Pack of 1)
I have tried a plethora of non-pharmaceutical anxiolytics, and I can say that CalmAid is by far the most effective. For me, the effects are comparable to a low dose of Ativan, but without the drugged feeling. Here are the main things I notice:
-Relaxed heartbeat. My heartbeat is usually very pronounced, but when I take lavender, it calms down dramatically.
-Quieter thoughts. I don't know how to describe this except to say that the "volume" of my thoughts is turned way down on lavender.
-Tremendous sense of calm. It's very hard to get upset or agitated or anxious while under lavender's influence.
-Improved sleep. I've suffered from horrible insomnia for a long time, and lavender is one of the only remedies that's had a noticeable effect. It doesn't make me drowsy per se, but it makes me so calm and relaxed that sleeping is easier.
However, there are some "side effects" (I use the term loosely) to be aware of when using this:
-Reduced energy. I suspect this is just the lavender calming my stress response and revealing fatigue that's already present to some degree, but it's worth noting. As I mentioned, lavender doesn't make me tired, but it makes me just want to kick back and chill rather than doing anything very active or exciting.
-Reduced motivation. Tying into the above, when using lavender I would often rather relax and watch a movie or read instead of getting work done. This is, I suspect, the dark side to being incredibly calm, whether it's lavender or something else making you that way. When you're calm, nothing seems to matter that much, including work. Ergo, you have less motivation. I think a certain amount of anxiety is healthy for optimal motivation, and lavender does away with that.
-For these reasons, I don't consider lavender an optimal anxiolytic for social anxiety, because energy and motivation are so important in social situations. I suffer from social anxiety, and have used lavender to deal with this at times, and though it does make me less anxious, it also makes me less social. I'd recommend something more like phenibut for social situations.
Despite these limitations, I still consider this an essential component in my anti-anxiety toolkit. I just try not to use it too often. Also, it's worth noting that human studies on lavender are somewhat lacking, and without more data, we don't know what the long-term effects of using it are. As with any drug (and I do consider this a drug), I think it should be used as little as possible. I would, however, much rather use this than a pharmaceutical anxiety medication.
A final note, on when to take it: I've found the best time to be 30 minutes before bed, on an empty stomach. The effects are more dramatic when taken well away from food, and if you take it before bed, you get the sleep-enhancing effects immediately, and the anxiolytic effects all throughout the next day (it lasts a looong time).

Effective, but gave me a headache
Size: 30 Count (Pack of 1)
I did and do like these. I find it takes the edge off my anxiety. Oddly enough, they give me a headache the next morning.
I tried only taking one pill at bedtime (instead of a second one halfway through the night); I made sure it wasn’t dehydration; I took electrolyte solution with it. I’ve pretty much eliminated anything else that a headache could’ve been caused by that I can think of.
They work well enough for me that on some nights it’s going to be toss up and I will still take it. But it’s kind of a drag knowing that something natural that works has a residual headache the next morning.

Day 1 and A Week ish Later
Size: 30 Count (Pack of 1)
I was taking Olly Stress Relief gummies for a while to control anxiety, hyperactivity and racing thoughts, and they worked great. Recently I noticed that they were becoming a lot less effective and started searching for alternatives. This was my first choice and I've only used it this morning. Took one pill. So far I have noticed a lighter mood, lack of racing thoughts, and an overall feeling of being slowed down. I can focus on conversations better, and it slightly enhanced my ability to taste, flavors seem more vibrant.. I am a bit more "lazy feeling" as others mentioned, and I did get the lavender burps. They're not horribly obnoxious for me, just a bit different. Burps lasted maybe half an hour. So far I like it.
Edit: it's been over a week now. The first few days I dealt with random headaches on and off, but did get benefits as stated above. After my body adjusted I stopped having the headaches and the "lazy" feeling. The lavender burps are still a thing and so is short term lavender breath right after taking a pill. You can describe it like a light lingering, kinda like toothpaste has a minty aftertaste, but lavender instead. For the most part I would still say it helps. It does not hit as hard as the first few days, but it is helping somewhat.
Benefits for me: Less overstimulation in public, better ability to relax after work, anxiety is more "inconvenience", easier to focus, deeper sleep, less irritability.
Cons for me: Short term lavender breath, vivid and unusual dreams, 2-3 day initial adjustment period for unpleasant side effects.
What I'm doing: Taking one pill around 7-7:30pm daily with lots of water. Taking late to sleep off any potential unpleasant initial effects, and get better sleep.
