Only you can decided is ML is too much for you to handle.... sounds like you're tired of being 'used' as a temporary fix. Don't beat yourself up too much, just decided what you are willing to put with and stick to your guns.
I had a professor that was a chain smoker (for 3 required classes). I always liked to sit up front because his voice was so soft- and raspy from all the smoking.... I used to wish I could shove my nose into a bottle of febreeze during class!! Sorry you're getting some unwanted attention.... I agree with 111, move to another seat if you can, before the semester gets too far along. Until then, maybe offer him gum every beginning of the class- maybe he'll get the hint. Good luck!
