My daughter has diabetes, and she sweats more than anyone I know. If she forgets deodorant one day.....whoa! I would suggest a trip to the doctor to rule out anything medically wrong....and if he checks out fine, then blame it all on the alcohol
My AH doesn't seem to sweat alot....but he has never really quit drinking for any length of time, so not sure on the withdrawal effects. His side of the bed is always stained, but he works in a plant that has many different oils and chemicals that end up in his hair and on his skin. It could be from sweating at night though, but I just always thought it was from his work.
