It does for some people. And you may not have taken enough. but if it got worse you're in precipitated withdrawal and you just gotta ride it out.
Try to keep yourself distracted with movies or video games or if you can stand it, go for a walk. Try to keep your mind off the pain. In my experience at least 75% of withdrawal is mental. And yes, that acute phase is absolute hell, but just keep telling yourself it will get better. I usually advise people on an OTC detox kit:
Benadryl/diphenhydramine (for sleep)
supplement shakes if you're vomiting to keep some nutrition down
loperimide (Imodium) go check out the lope megathread if you're unfamiliar with this
movies
baby wipes (you'll stink getting all those toxins out and won't want to shower)
And if you cn get your hands on some gabapentin for the RLS that'd be great
Good luck, we'll be here to help you through it, but you can do this.
