Quitting either one is really hard. I think quitting smoking may be the hardest but giving up drinking was a massive undertaking that took years to get around to. I quit drinking twenty years or so after I gave up a heavy smoking habit. I got through the cig withdrawals by drinking lots of crappy beer. Quitting drinking didn't even occur to me back then!
I don't want to sound harsh but if you need to quit both habits then do it! Stop making excuses. I'm currently fifty years old and my old smoking buddies who didn't quit are starting to die and it's gross and pitiful! What do I tell my kids when Aunt Julie dies of lung cancer? Uncle Steve strokes out at 61? Of course I tell them don't ever start using nicotine but it still sucks!
The best thing about quitting smoking is that after a year you're golden. Drinking is more insidious in my opinion. Remember, nothing is going to make you feel better about quitting either one except time. Just don't start again and things do get better.
