You need to tell your doctor about the effects you are feeling. It's important for your health.

Avoid that pills and eat some veg..

Diet pills are probably not your best decision. I am absolutely sure there is another solution to weight loss for you. I just saw an interesting Youtube video
there is a lot of good healthy information out there for you.
