Hello I'm looking to gain weight

Hi, My name is garry. I'm looking to gain around a stone in weight. I'm 21 and have weighed around 8-9 stone since 2006. I'm now upto just around 10, but looking to put a healthy stone on. HOPEFULLY of muscle. So that I meet a natural weight.

I've had eating disorder of sorts before. I used to count calories like mad but I also drank a lot of alcohol so it balanced out (sounds terrible i know!) or I would have been stick thin.

Hoping to have a healthy happy future, with food OFF my mind 24/7 and eating healthy, cheers.
