I took one 20mg tablet at 10:15pm last night (about an hour or two after I had a bad panic attack). I was really tired for a couple of hours and then I got a sudden rush of energy and it sounds good but it wasn't as I wanted to do stupid things. It settled and I couldn't sleep for a few hours as I got very hot.

After waking up this morning I'm shaking and have hot flushes plus the back of my brain/head feels cold too I don't know if that's normal or not. I'm a bit more anxious even if I am not thinking of anything can anyone put my mind at rest?

Thanks.
