Hey Milo, sorry I didn't reply sooner, I've just gotten around to reading your post right now.
No I didn't put the 28 lbs on in 2 months, that would be a lot of work and wouldn't allow for much time to recuperate as you suggested. I started out at 136 lbs in September of last year, I breifly went to the gym during the fall but quit in October after my gf moved out (we had been going to the gym together). Then I started eating a little better and in Janurary I got back to the gym occasionally. When I started the polyphasic sleep, I stopped going for a week or 2 because I wanted to adjust to the schedule without wearing myself completely out. After that I was going to the gym up to 6 times a week, so with my diet, the Whey protein powder and HMB pills (all of which I explain here: http://www.solegoal.com/2006/03/how-do-you-shape-up/) I reduced my recuperation time and felt a lot less soreness then I normally would. I managed to get up to 170 lbs, I'm at 166 lbs right now, having lost a few pounds on the treadmill but I have a goal of 180 lbs in the next few months.
My quick reply to David's post made it sound like I'm sucking back the 'roids but that's not what I meant, sorry for making it confusing. :P
