I once read somewhere that the bruises are accually a cause of the alcohol, not a pain inflicted bruise at all.
I feel your pain, i look back at all the nights i passed out with a baby in bed and how easily it would of been to roll over and suffocate them.....awwwww the feeling still turns my stomach even thinking of it.
Keep coming here and you will find this place a big help, it worked for me i am 6 months sober and maybe in june or july you can be to.
As far as sleep.....i drank to sleep as well, now i take anti anxiety pills before bed and sleep sound all night.
Good luck and keep postin
