Hey Char,
I actually just started P90X about 11 days ago and am blogging each day about it. Feel free to drop by my blog and subscribe to my RSS feed...
P90X Review & Workout Plan Results
It really is a very intense program and I've had several days of nausea, but it's starting to get better now. Even though I'm only in week two at this point, I'm already seeing some results.
Good luck!
