My girlfriend looks away or buries her head in my chest when I look at her. Same thing after a kiss as if she is really shy or uncomfortable, but she loves to cuddle on the couch and in bed. I just can't figure her out. When it comes to sex she openly admits to NEVER being in the mood unless she's been drinking or sometimes in the morning when she is "filled with energy". She looks forward to drinking and acts like she has ADD when she isn't. She had a drug problem in her past. I care about her! What should I do?

Im not sure if I can offer good advice, but I think I would start by sitting down with her and listening. Asking her if something is wrong and trying to make her feel comfortable. Maybe she is very shy and needs someone who cares, which you obviously do, so tell her that and try to listen her.

Good luck.

Sounds like a self confidence problem, girls are so hard on themselves when it comes to looks and their bodies, just talk to her and tell her she perfect in your eyes her drinking
It might be a sign that she a real drinking problem or maybe she just can't relax enough and tell she drinks which is a cop out, you I used to say that till ended up with a real problem drinking just lets you do things you normally wouldn't.. Talk to her and see what she says

Best of luck

Drinking to feel comfortable in social situations is not good and can only lead to more drinking. Try going off out for the day just the two of you no where near a bar. Just spend sometime walking and talking. Let her know how she makes you feel.
