Just wanted to say I hope you are feeling better, and please be very careful not to ever take that or anything similar again the reaction is often worse the next time. In addition you should be tested to see if you are allergic to anything else. Allergies can develop as we age so you may not be able to have things that you once could. Also if you have medical allergies you should get a necklace or bracelet to wear telling anyone about it, or at the very least make a note and put it in your wallet. Good Luck!
