I’m at day 37 right now and of the opinion that I am still not fully in my right mind. That is, while I feel better in a lot of ways (not ALWAYS anxious or angry like during the first two weeks), I am still going through slow waves of, like you say, loneliness, boredom, tiredness and more. This is part of getting better, of feeling better, and also finally seeing what really does lie on the other side of life from weed. As such, I am going to keep not using weed, and based on one earlier quit 5 years ago, I expect things will improve more around 90 days. I hope you’ll keep going too. 40+ days is great. What I always tell myself is there’s no need to ever go back in that cage.
