Definitely go with the pills if at all possible. Trying to drink a gallon of the other prep is torture. I couldn't even get it all down - tried to force the issue and ended up bring it back up.

And I don't know if anyone else ever had this problem, but the last one I had really took it's toll on me. I was going to say "took a lot out of me" - but that's obvious!!!

The final part of the prep I had to do before I left the house - I was really feeling lousy and lightheaded. I stood up to leave the bathroom - took a few steps and made it in to the bedroom - and promptly passed out on the floor. I came to right away and was okay after sitting on the bed for a few minutes. So if you feel lightheaded at any point in the prep - just sit and don't try to get up right away - just take some deep breaths and let it pass. Wouldn't want you to break something or crack your head on the way down!!! Not trying to scare you, but my doc said it can effect some people that way, altho it's not that common.
