Wait it out.  Phentermine is nothing but caffeine, and the pharmacist and doctor should have told you to reduce your caffein intake.  If they didnt, then it was in your package insert when you get the medicine filled.

Right now all you can do is wait it out.  Rest, drink lots of water and NO MORE ENERGY DRINKS.  Never, ever do that again.  You are going to cause yourself to have heart problems do to the excessive amount of caffeine.  Its bad enough that you run the risk of heart problems with Phentermine but adding energy drinks to that just adds to the risk.  I took Phentermine for a while.  I never drank energy drinks because I cant stand them but I now have heart problems because of the Phentermine.

I would not go to the ER at this time. It is most likely a reaction from the mixture of Caffeine and the diet pill. Just learn from this experience and dont mix it again. Always safe to ask a pharmacy if you are unsure.

I would go to the ER as soon as possible, they may need to give you an anti-dote to counter act the reaction.
