Are there any risks to drinking red wine every night before I go to sleep?

I have a lot of trouble sleeping, I mean a lot. I know that I have even a little alcohol in my system it will help me fall asleep faster. So I was thinking I will drink a little bit of red wine every night before I go to bed, I'm talking like 2 shot gles worth, not even a gl. Are there any long term drawbacks to this? I always hear that red wine is good for your heart and what not.
