I think the diagnosis will probably hold up. I don't have BPI, but I have BPII, and my story was kind of like that.

You should *try* and minimize the amount you are drinking while taking mood stabilizers. Monitor your mood. It's a good idea to start journaling/blogging, or you can use a website to. (I forgot the website name at the moment) This can make it easier for your doctor to see whether or not you're feeling okay. Eating healthier and working out can help minimize side effects, too. Finally, make sure you read the labels on the medication they prescribe. It's important to know the side effects and what the purpose of the medication is. Give yourself power.

WHATEVER YOU DO: Do NOT quit taking your medication the moment you feel better and stable. If you ever want to start taking less because you're feeling better, talk to your psychiatrist first. Or therapist. Or post here. I spent 2 years after my initial diagnosis in and out of doctors offices wracking up the bills because I thought my diagnosis was incorrect. Time and time again, I learned that I am bipolar. x)
