I had stomach palpitations yesterday, how long until my stomach ache goes away?

Yesterday I had 2 caffeine fat burners (JST Jodie Semtex), a few hours later, I felt really sick with extremely bad stomach aches.

I was sick and I feel better now, however I have an intense aching pain which has not subsided.

Does anyone know when this will go or should I see a GP?

Thanks

Yes you should see a gp. Once this problem is sorted out, remember to stay away from caffeine if possible and get plenty of organic fruits and vegetables and organic food in general. Regular is not good for you.
