Cool man! I actually just went cold turkey on everything 3 days ago.
Two summers back my parents booted me out of the house and went to a detox program for 4 weeks. When I got back I had to land a job and move into a room for 6 months. the other year and a half I stayed with a friend in an apartment the next town over from where I used to live... Well, he was still a heavy pothead/drinker. So, I continued to smoke and drink (weed daily, cigs on and off). Anyways, we didn't end up respecting each other and told me to leave. I'm back at my parents basement (haven't lived here in two years)... It finally feels like I got back from a two year sentence.
But, you know what's weird? I don't want to do drugs anymore. My parents aren't even making me quit. I get along with them much better than two years ago, after all this, and will have a glass of wine at dinner and such. It's just that, I don't want to consume myself in tobacco, nicotine and alcohol anymore. I just end up being in the same rut I always was in. It was hard not to when my room mate was selling to me the whole time I was living their.
Now that I'm sober, I find stuff to do like yard work and gardening during the day, I'm also starting two online classes for the fall. At night, when I'm not stoned, I get really depressed, especially thinking about how I'm in a town that I grew up in, and now I don't talk to anyone anymore and a lot have moved away. I like the space, so instead of feeling like I can't go on being sober. I do exercises, eat healthy, and go on midnight walks around town to boost serotonin into my brain. I hope that in a month from now I will finally get into the shape I want to be in, and be completely THC free. Then, I can land a job that isn't a bullshit job and won't relapse. I haven't done psychedelics for two years. I wouldn't mind if I just stopped consuming all my money on drugs, and eventually promote myself as an artists and perhaps travel.
Cigs are just one thing, if you continue tripping you may pick up cigs again, I've done exactly what you've done a couple of times, try to cold turkey! Thanks if you read this far!
