Your situation sounds pretty similar to mine actually, only I supplement with Lope instead of Subs.
My only issue is that the 3-4 days a week that I use I typically BINGE to a level that it negatively impacts my social and professional life in a significant way. I'm definitely taking a break very soon, and hopefully I can stick to it for a while this time because I need more than just a tolerance break, I really need to try to quit again. I had 2 years clean and those 2 years were definitely the best 2 years of my adult life, its just so damn difficult to quit when FIRE dope is 10 minutes down the road all the time
