"i am about to finish my second month on phentermine and i am down 32 pounds! i feel great! the worst thing is the constant dry mouth, and taste in my mouth i constantly have, and i have no desire to ever drink. but i have a question for anyone else that is on this, has anyone else experienced serious mood swings, or just a complete behavioral change in yourself? since i have started this medication everything seems to annoy me or piss me off?! kind of weird but i figured i would ask to see if anyone else was experiencing the same change?!"
