You might also try googling FMLA, a lot of variables.
Obviously your drinking is having significant fallout, sadly it doesn't get better. What are your plans to get sober?
Managing the areas affected by your drinking is only going to become more complicated when the main issue is not being addressed. I am not trying to be harsh, I am concerned.
Do you have any sort of plan for getting sober? I see that rehab was suggested. I did 30 days of inpatient, it helped me tremendously, and gave me a good start and a good focus for when I got out. If it is possible for you I can't recommend it enough. I thought rehab was hardcore, it's not. When things are falling apart around you because of booze, it gets serious. This is a critical time in your life.
