Phenibut for insomnia

Ambien will not put me to sleep so I take phenibut to lower anxiety levels. Wiith using phenibut and ambien together I sleep great. It is also useful during the day to lower stress and anxiey when needed. I take it every night.

I had never used Phenibut before a few months ago. I had heard good and bad things about this stuff. When i first started taking it, i liked how it made me feel. I seemed to be in a much better mood than i had been in the past. It also seemed to help me sleep once i finally laid down. I did not contunue to take it for a long period of time. I had heard and read that it can be addictive. Not sure how true it is. So im not sure if i would recommend it or not. I guess it depends on what ur looking for.

Quality relaxation product

So, when I first started taking Phenibut, I felt like I was a non-responder. I stuck to the recommended dosage & followed the protocol of only taking it for a few days, then taking time off. Do some research & you'll find info about it's addiction potential & horrible withdrawals. So I played it safe, & thought it wasn't working. Then I upped the dosage a bit. I've found that 3 grams is my sweet spot. Gets me nice & relaxed, & helps me fall asleep, without even trying. I've always had a higher tolerance than most for medications, alcohol, etc. Phenibut is no different. And after taking 3 grams at night, I can still somewhat feel the effects the next day, not making me tired, but just taking the edge off of my social anxiety. As far as the scary addiction stories go, I've experienced no withdrawal when I don't take it. I take it 4-5 nights a week to help me sleep when I need to be up for work the next day. I don't take it on my two days off. I recently took a vacation from work & didn't take any phenibut for 9 days; no issues. If you suffer from anxiety, insomnia or both & are looking for something non-prescription to help, try this. It works!

Great product

Phenibut XT is great. puts you in a great mood, causes relaxation, and aids your sleep. Only downfall, is the fact that it can be addictive, tolerance does build up, and apparently there can be withdrawal symptoms. I haven't experienced withdrawal symptoms, but others have reported it. Overall, I really enjoyed this product.

great product

Really interesting ingredient, good quality phenibut. Extremely relaxing, will put you in a good mood. long lasting effects. Will have a great nights sleep using this product. i built tolerance fast, unfortunately, but the product always worked as indicated even if I had to increase the dosage nearing the end of the bottle. Would not recommend daily use, as it seems to be fairly addictive, but the product worked great for me using it a couple of times a week.
