I know that this is correct: Since you are an alcoholic, you need to drink less.
How about this: You need to drink less, since you are an alcoholic.

I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
Thanks noted. On a side note, this is definitely NOT something you would say to an alcoholic.
As an additional note, there are people who claim that "since" should not be used to mean "because" but this belief is not very supportable. There ARE times when using "since" can cause confusion because it's not clear if it refers to the period of time, or to mean because, but this is not one of them.
