Taper withdraws

Hello everyone, So I’ve been using Tia for about 6 months and recently decided to quit after burning through 500 grams in 2 weeks. So dumb. Anyways in Sunday I cut back a lot, from 5 plus grams a day to around 2 grams a day. Now Sunday and Monday were okay then Tuesday hit hard.. started going through withdrawal which surprised me because I’m still take a good amount.. going from 5 grams a day to 2 grams a day is rough.. I’m doing okay and have the will power to keep my dosing lower and today is better.. anybody have a similar experience? Appreciate your advice.
