i have been bulking for a about 6 months now and i have gained alot. recently when ever i sit on the computer chair i get the feeling my stomach is pushing itself outward, i sometimes wrap something around my waist and make it tight when i sit down to just force my stomach inside, i have gain alot of fat around my belly. but its a weired feeling is it from drinking water alot , i drink about 3.5 litre a day.
