I’d be careful with the Red Bull.  Like Tonia said, it can be very VERY addicting.  Lots of college campuses are having problems with kids who are drinking far too much of it, becoming actually addicted, and suffering from a racing heart (tachycardia) and possibly fibrillation (when your heart beats out of rhythm).  I think if you have a thyroid condition (either hypo- or hyper-) and things are already off-kilter, it’s probably not the best plan to exascerbate the problem with mass amounts of a very powerful stimulant.  Now, I’m not a doctor or anything like that--it just seems logical to me.  As far as the CAH goes, I’m not sure if that comes into play that much. I’d be more concerned with the thyroid.  Again, I’m not a doctor but it’d be a good idea to consult one.
