sleep was definitely a problem for me when i first got sober.
i also remember once, in my first year of sobriety, that I didn't get any sleep for about a week. every night i would try to sleep next to my wife and i couldn't...eventually i would go to work in the morning feeling exhausted...i'd come home, go to a meeting, wind down, and couldn't sleep. it became a nighmare and i remember feeling scared that i would never sleep again.
