I’ve been using f-phenibut at doses between 400-500mg/day for about 45 days, how long should I taper? How bad do you think the wd’s will be?

So I’ve been on a somewhat steady dose of 500mg/day on f-phenibut for a month and a week now. I started off just using2-3x a week but then started daily dosing (dumb I know!) anyways I’ve had maybe a few days here and there where I’d dose 800+mg cause it was working really well for social anxiety on days I’d be in a social outing. But I still have something like 11g’s to use to taper, and was wondering what my taper schedule should look like. I have also maybe 11 caps of Agmatine and a lot of gabapentin, and an oz of regular phenibut hcl (although not the best quality-Nordic chems) Any help would be much appreciated guys thanks!
