I?m a long time Phenibut user (once weekly, maybe a handful of times twice weekly over the last 3 years). I used to use HCL and I switched to FAA for GI purposes. However, I now have some of both. I wanted to try the HCL again after several months off, but out of habit, I took FAA without thinking. When I go for my second dosing of the day, can I use HCL? I know there?s no actual danger but I didn?t know if anyone experienced maybe a weird hangover or anything like that. Thanks guys!
