Eating/Drinking??? (PLEASE READ!)?

That's definitely something to see the doc about. Speculation: your thyroid has grown and is blocking your throat. Not to freak you out, but have you been tested for thyroid cancer (don't worry--it's not a very dangerous disease, as long as it's treated early)? Go see an endocrinologist, if you haven't done so yet. The hot flashes could be due to a number of things. They are an indication of hormone weirdness, which can happen with low thyroid, or with high thyroid. The thyroid and ovaries are closely tied in their functioning, too, so for example if your thyroid isn't working well, your ovaries may not work well in response--but fixing your thyroid will make the ovaries go back to normal.
