My review of excedrin starts by saying the product works extremely well. I can honestly say i have used excedrin for many years for chronic headaches. It would take my headaches away in as little as 10 minutes. They could never find what caused my headaches over the years. I found out on my own i was addicted to asprin. That is something they don't tell you on the warning label. It took me many years to come to this conclusion. I wound up because of asprin usage with bleeding ulcers. The worst part was that my ulcers didn't respond to medicine. So finially, because they were worried the ulcers would perforate, i had to have surgery and two thirds of my stomach was removed. The bottom line was that the excedrin worked to good. It definately holds up to be true on what they advertise on thier commercials. But i feel they they should tell you, that just because it's asprin, an over the countr drug, it can still become addictive. That is a very important bit of information. I haven't taken excedrin in over 4 months now and what i found was thast my headaches went away. The first week was very hard, it was like a drug addict coming off drugs i guess. But i later found out the more asprin you take, the more you need to get rid of the headache. It was a constant cycle.
