first of sokrates, psyco DOES have experiece so u won't have to wait around for somebody with it.. 2nd, there is no too much weight, or too little for god sake!! just look in the mirror and if u think that you're lookin a little chuppy simply cut down on the cals... simple as that...
so if u did gain 20 pounds in a week, the only person to say that it too much is YOU... so chill out.
