Ok, so I have issues with substances as well. But it seems to me, (and I say this gently) that if you can't just stop the pot with no effects or if you're not willing to, perhaps you are addicted to it. Perhaps smoking weed is not the answer to keep you from drinking. Both weed and alcohol are depressants, and if you have a mood disorder, this can wreak havoc on you. Also, drinking that much alcohol is a problem, especially for someone on meds of any kind. If you can't stay away from pot or alcohol when they are both contraindicated and the pot is against the law too, then maybe it is time to look into seeing if you have an addiction problem.

Just my 2 cents which you probably don't want, but I wanted to share with you a different perspective. I wish you all the best in whatever you decide to do.
