dress used for bridesmaids and designed for proms

I have a strange reaction the day after taking Tylenol Pm. My heartbeat increases plus, loss of breathe, feel tired all day, and get dizzy. This is supposed to be just a combination between Tylenol and Benedril. These are also common side effects in pregnancy, but this happens every time I take it. Usually, I avoid it and only take regular Tylenol if the pain is too much and causing me sleep issues. I ran out of it and the only thing left was that. I only slept for a few hours the night before and was in so much pain I was crying. It took away the pain, but now have the above symptoms in its place. Has anyone else had this issue with Tylenol PM? dress used for bridesmaids and designed for proms
