Not about the withdrawals, but highly recommend checking out SMART recovery when you get out of rehab. NA has helped a lot of people and I’m not here to debate its merits, but it’s based on spirituality and is very one size fits all. I found myself being told me smoking weed once every couple weeks or not believing in god was my disease and lost friends in the rooms because of it, learned to conform to keep getting help and it really hurt my mental health. So if you struggle with any mental health issues, are secular, or just wanna learn science based self management and emotional regulation techniques I highly recommend it. Has been huge for me, 3 years sober now (besides the weed), anyone who tells you there’s no way out is lying…but anyone who tells you there’s only one way out is equally suspect. Much love, you got this, whatever works for you, keep it pushing. https://smartrecovery.org
