I've made a new account for this because its frankly embarrassing.

I've wanked every day, sometimes multiple times, most days I have sex and still wank. I understand this is a learned reward behavior in my mind, I have to break, but when I try I relapse due to these two problems:

It seems every time I give up my girlfriend wants sex and shes a nymphomaniac so its pretty hard to refuse her. I've looked for sex addicts anonymous but can't find any.

For the past two days I've stopped fapping. I have got my head in the right place at the moment, but its stopping me from sleeping. I'm getting awful night sleep or non at all. Each time this happens I'll fap and then I can sleep.

I've tried sleeping tablets they leave me tired and I over sleep, my work suffers I'm basically a zombie and I've tried a couple types, I've even cut down to a quarter of a pill. I could try less but I know it would leave me much the same and its not acceptable. I need to be sharp minded in my job unaffected by sleeping drugs.

Has anyone got advice to help me with this sleep difficulty?
