Hi copacetic,
I can't comment about the lack of a gall bladder. You're making creatine supplementation too complicated. All you have to do is mix a tsp in water (or whatever your drink of choice is) and drink. That's it. It doesn't matter when you do so just as long as you ingest the stuff each day. Hell, I mix creatine in my evening coffee. (For those who claim caffeine interferes with creatine, I call b.s.) About the only thing that does matter with creatine is the quality of the powder. I'd only buy a creatine powder made by either the Creapure (german) or Pfanstiehl(usa) labs. If you do the post-workout-shake thing then it's fine to have creatine then. No, glutamine and protein won't interfere with creatine.
