Yeah, but sometimes what they prescribe you ends up effecting another part of your mind or body. You can't truly rely on what it is they give just because they have the title of a 'Dr.' Lol. What you should do is research and look up your symptoms and compare them to the one's your Doctor said you had. Then after that, just think of your solutions that are at hand. You could rely on your meds or what your Doctor says, or you can find out for yourself and then discuss it with your Doctor to see what other options it is that can be made available.
Drinking should never be a solution, though. But that's just me.
