Hey Yoyo, I have gone through a few different CT detoxes (opiates were my DOC) and it's never a picnic but just keep in mind it WILL get better. Your brain chemistry is trying to recover after getting all those false signals from the drug all these years. Consequently in addition to the physical withdrawals there's always the mental stuff - which is possibly tougher. Hang in there, you can do it. Try to keep yourself busy once you get past the worst of the physical stuff.
I see you mentioned kratom withdrawals being tough. I try to educate people on that because I just went through a terrible experience with the same. Honestly it was worse than kicking pills. Not enough people realize how powerful that stuff is.
