Does anyone else experience self-destructive periods?

Whenever I'm stressed or depressed I crave alcohol like it will bring some relief to me. I enjoy the time I'm drinking, which most of the time is alone but regret it every morning after. I hate the fact I drink and I've never been able to drink socially, only to get drunk. But still there is something comfortable about that state from when I have my first drink until I pass out. I have been given Naltrexone from my doctor to treat the craving but it seems to be something that comes and goes with my moods. I can easily go 6-8 months with nothing to drink no problem, but it seems every now and then I get into a self-destructive state of mind where alcohol seems to be the answer to everything. Does anyone else experience something like this?
