I woke up this morning around 5.45am heart pounding and feeling like its bouncing all over the place, shaking all over. Ran to the loo as had tummy ache and nausea. Heart rate fluctuating between 88 and 137. So I took a diazepam 2mg. 6.35am now and heart rate back down around 70. I just don't understand why this happened. I was only dreaming about knitting! Glad I'm working from home today because it really frightens me. Does this happen to anyone else?
