I think that headaches and nausea are definitely possible side effects of too much caffeine - I know a couple people who can't take any ECA type products because they get these symptoms. Caffeine can be used, in adjunct with aspirin to help headaches though...so I guess it swings both ways.

I would listen to swole and increase your water. Water is important, but can be even more important when using thermogenics. So your first step is to increase water intake...if you're still having symptoms, then try backing off the dosage of Xenadrine a little.
