Back when I was lifting fairly regularly there were a lot of periods of times that I wasn't able to get a good nights sleep. I found that I was actually able to get in a pretty good workout even when I was tired when I was on a creatine cycle. Now that I'm in grad school for the next couple of years it looks like I won't be able to banish sleep deprivation completely. But riding on little sleep for me is horrid. Are there any sleepless people out there that have used creatine to resolve this?
