i was stuck for about three weeks....just TODAY my scale went down. i was telling myself it was just plateau, but yesterday i really got focused, drank TONS of water, and ate tuna and fruit and ta da! so, yeah....you could be stuck for no good reason if you haven't changed anything. just take a look at what you've been eating, have you been drinking enough water? and if not....change it. if so, just wait it out.....it will go down again!
