severe headaches

I was very disappointed. I have taken this for 4 days and I get a severe headache about 2 hours after taking it. The headache lasts for about 6 hours(am guessing thats how long it takes to get out of your system). After the headache goes away, I feel really good. Guess there is something in here my body does not agree with.So if you get a headache after taking this, dont keep trying thinking it will get better, it wont.
