I say maybe stop the alcohol first but also set a date to start tapering back on the weed as well. Do you have a support system to help you in stopping?

I agree you need to be realistic and it may be easier to do one at a time. I think that once you start getting rid of one, you'll start to feel healthier and the other will start to be easier. Also remember alcohol has long term effects to your body as well.

Good luck with this!
