My workouts would go so much better if I had a normal sleep schedule.
I used to hate getting very little sleep when I was building. Though I felt better when a guy I know - who was going for, and won best newcomer in Mr Scotland a few years back - was a bus driver working 12 hour shifts, working out in the morning and evening staying awake only with a combination of bizarre pills.
Made me feel a little better for getting four-six hours when he was getting one or two.
On me - I've been doing light workouts since dropping to under 180. By months end I intend to go back to my old schedule (or maybe find a new one) to get myself back up to a reasonable weight before a gig in January.
I'll feel a hell of a lot better on some heavier weights.
