Being Vegetarian-Hungry ? weight gain?

You're a victim of what I like to call "Sh*tty Diet Syndrome." This means you had a sh*tty diet as an omnivore, then just cut out the meat, leaving you with a sh*tty diet. You shouldn't gain or lose any weight going vegetarian...since you did, you're doing it wrong. You're overeating, eating too much crap (that's why your skin is breaking out), and not exercising enough. Fix that and you'll go back down.
