I know I'm being a pain tonight but I'm having some real troubles tonight. Every time I try to sleep surges of energy goes through my body and then it settles in my chest. Also as I stated before I'm shaking and it feels like my heart is beating rapidly (even though the highest rate has been 84 bpm) and my heart feels like it is going pound out of my chest. I've tried reading, taking a shower and watching tv but nothing has helped. I took a 25mg xanax at 9 pm and another at 1pm but it hasn't helped. Any suggestions or help. I feel at the end of my rope.
