I messed up big time I’m at the same dose as you man, here’s my advice, I’m going to be trying it as well. I’ve had to taper off phenibut in the past and what works for me is try cutting your dose as much as possible to find a stable dose. Start by cutting to 10 maybe, as low as you can without major withdrawals. You might feel a little shitty but find the dose that will make you feel just “normal”. The best thing to do is not panic and HAVE PATIENCE. Patience is the key to getting off this shit and I’m trying to teach myself too. Once you find a stable dose, taper off that. Take a small dose .8g or so before bed as well just to help with sleep. That is what helped me when I tapered off 7g in the past. Had lots of success cutting to 3g from 7 and tapering off. Then I fucked up and started taking it again to land this huge job I’ve been going after. Luckily I landed the job but now my tolerance is in the same spot you are. Don’t take phenibut to get “high” anymore. Find a stable dose that doesn’t send you into full WD and taper from there. Patience is the key to getting off phenibut with very minimal withdrawals. I know it’s hard because there’s really no easy way out but you have to be patient with it. I’m in this with you man. Good luck.
