Sounds like you are just bored with sex desu. Try something new. Maybe some fetish you never thought of with your partner.

I am no expert, so take what I say with a grain of salt.

I could see this being 1) psychological. Something is keeping you from getting it up. Worrying about it could be making it worse, like a performance anxiety. Like when you worry so much about getting enough sleep that you can't fall asleep.

2) could be a diet thing. Take better care of your body, try to sleep more, get exercise, etc. That being said, I have been smoking cigs for almost 10 years and never had a problem with my weiner.

I'm going out on a limb here, but from my anecdotal experience erectile dysfunction is heavily related to psychological problems such as stress, anxiety and depression. You could still seek a doctor for help but you should certainly look into the amount of stress you're experiencing. The fact that you're smoking and drinking seems to indicate that you're trying to cure the stress that way to me, which isn't really productive.

TL;DR - I think it's likely due to stress.
