I'm not even sure you should be taking serotin with your other meds. I have no idea what would constitute an overdose of this suppliment. I have no idea if this could produce an anxiety attack and lastly, I have no idea how long you are going to feel shaky, weak and have stomach problems.
What I DO know is that until you learn to take medications as prescribed, you will continue to have problems.
Call your doctor or a pharmacist!
