Ive never done meth but i read a book called tweak written by nic sheff. He was an addict and wrote a memoir. He did meth and needed to enter a rehabilitation center a lot of times. I hear the withdrawals are terrible. My mom does meth and has been in several rehabs. I knew a 14 year old who did meth too.
I dont know what state of mind you are in or will enter as well as your physical health and its better to be safe than sorry and enter rehab. Its not going to be fun, no one wants to do it, but its the right choice.
Ive entered a locked institution before that helped me stay clean from substances. I was there for five months then entered a group home. Ive also been on house arrest and been drug tested almost every week by the court and that helped me stay clean.
Why risk using again and suffering from health problems when you can do it the safer way. Yes its likely youll use after rehab but they can seriously help you if you let them.
Look man, ive had some shitty withdrawals before and i cant imagine what withdrawling from meth cold turkey must be like. The possible temptations, the "bugs" crawling in your skin sensation, the paranoia, the insomnia, the seizures, etc. They can give you medications to help you withdrawal if you go to rehab.
Whether you believe it or not eight months is a long time man. If it was a one time thing or within the span of a few weeks thats a different story. I did heroin within the span of a few weeks. I went cold turkey after the cops found heroin on me and the withdrawal was shitty but not nearly as bad as long term users.
You got this
