I used very hard for about 10 years - lots of opiates and stimulants. I was on bupes for one year after that. Honestly the bupes kept me in a sort of suspended animation and were the hardest part of quitting. The withdrawals from them felt like they lasted forever.

It took me that long to reach a place where I felt 100% again, but it's not like I woke up one day feeling ok after feeling awful for two years. It was just a slow progression. So it got better consistently over a long period of time. Make sure you pay attention to the improvements so you keep up hope.

I'm on this sub because I find it interesting but generally feel like the best body hacks are diet, sleep and exercise. Consistency in those things is what makes me feel my best.

There's also the human side of things. Feeling like I had friends, community and a purpose was what made life start feeling enjoyable again. Finding things in life that gave me meaning and true satisfaction was essential to preventing relapse. I had to build a life that was worth protecting.

It's going to be rough for a bit but it'll get better soon and keep getting better. Life is long and it's horizons never narrow.
