I remember being really addicted to substances as well. I feel like it helped pass time a lot. But it never gave me any productivity , it was always wasted time and usually a trip to the hospital. Even as i type i have craving for it. But because i know it doesnt do me good. What is there to do but avoid it altogether!
I hope you are able to keep avoiding it. Because it is so bad for mental health and keeping routine. And routine is what keeps us as stress free and therefore psychosis free as possible
Pot was ok before i was psychotic and id smoke every couple of weeks with friends, then i went through a bad breakup and started smoking everyday i didnt even get high anymore i was just maintaining a habit. Then when i got schizophrenia it would cause anxiety and an hours worth of voices total panic attack. Id like to go back to the old days of every couple of weekends but its just not possible if i use once ill spend 3 days craving it all day which goes away but thats 3 days wasted.
