I can relate. When I get stressed, like today, I will take anything to try to sedate me. Benadryl doesn't faze me though. The doctor has prescribed me medication and my husband and mother monitor my dosage just in case. I try to think of something positive which can be hard when you are panicing and your heart is racing. The breathing technique works, but when you are extremely stressed it seems that you follow with the panic. Do you ever get so stressed you start crying? I do and I am having one of those nights. I have already taken a xanax and a muscle relaxer. I am having a muscle pain from an old injury to my arm.
