How to get off this stuff

Guys I’ve gotta get off this stuff. But I don’t know how. A few days ago I ran out and started having immediate withdrawals. I’m not sure exactly how many mgs I take daily.. but it’s a lot. I’ve been taking it for a couple months now. Prior to it, I was on regular kratom powder for about 9 years. Anyways, the withdrawals I experienced were SO BAD. I didn’t have any for about 30 hours and I wanted so badly to not give in but I was miserable. My symptoms were server RLS, cold sweats, nausea, terrible stomach ache, body aches, not able to sleep or get comfortable.. I mean.. it felt like I had the flu times a million. I took regular mit powder but that did absolutely nothing. I literally wanted to die. So…. With that being said… I NEED to get off this but don’t know what to do. I need advice. What steps should I take? Any advice is appreciated. Love you all 💕 and thank you for the support.
