I've had some pretty long ones, I used to have a kidney disease in which my kidneys leaked protein ijnto the rest of my body, so I would become all swollen. the doctor would give me meds to "flush" my body of it all, and I would basically just piss alot, very often and lose madddd amounts of weight (im fairly average sized as well, 6'1" 180). One weekend I lost 45 pounds and noone recognized me in school the following week.
