Hey Anik,
I would say about a month. It wasn’t steady improvements either. Some days were easier and some days harder. Also, even after the first month, I would still descend back into a foggy/anxious state after drinking for about 3-5 months after quitting. Masturbation would also have similar effects.
Essentially, I would be feeling like everything was improving, then I would drink or masturbate, and that would tend to push me back into an anxious state.
I don’t mean for this to sound as though these are the two solutions to PFS, but no alcohol, no masturbation, and healthy living really helped for me.
During your 3 weeks off of fin, have you noticed any serious improvements?
