It made me sleepy at first. They normally will have you start taking it at night. I now take 900 mg , three times per day. Unfortunately, I have gained quite a bit of weight and the burning is now back on the top of my head. I do not want to increase the amount I am taking which will probably be my neuro's solution if I call. I have tried to slowly cut back on the dosage on my own, but have not been successful.

Jenn, I did not know you could take it on an as needed basis.
