withdrawals from 3.5 years daily use has been horrible

I’m a long time user been on and off for years starting in like 2016. back then i never went above 2gpd 2-3 times a day. barely felt any withdrawals just jitteriness. i started taking it again in like 2020ish, everyday, every 2-4 hours from 4-15gpd. imagine my surprise when i stopped taking it yesterday and the past 24+ hours have been absolute hell. on top of that my dumbass started a new snri medication too. so those side effects have made it a bit worse. the rls and very little sleep i think has been the worst part. it makes me want to jump out of my skin it’s such an awful feeling. at one point i thought i was gonna need to go to detox or the psych ward for their medications. i’ve come off other stuff too but i never knew kratom could be this intense. i’m gonna try to taper from now on i cannot go through that again. if anyone has any tips pls let me know.
