Has anyone tried the T25 ActiVit Vitamins?

I ordered the Metabolism Formula with my T25 workout. I took 2 on Monday with my meal as instructed....2 hours later, I had a pounding headache and my stomach was not feeling right.

Has this happened to anyone else?

At this point, I'm afraid to take another dose. I want to know if this is normal when you first start taking them before I cancel the order.

Thanks!
