On thursday night I took 500mg of DXM. I was on buspar at thr time for anxiety. The next day I woke up feelimg very disoriented and lethargic and numb. I discontinued the buspar and the feeling has continued. Yesterday I went to the emergency room and had a blood pressure of 180/100. Today I got checked again and it was down to 125/88. What could have happened and will I be ok?
