This is really me clutching at straws. But up until 2 weeks ago last Friday I was taking 20mg propanolol (not slow release) at bedtime. I stopped when I went on holiday basically because I forgot to take them with me/they fell out of my bag. I was still taking 25mg promethazine which helps with sleep.

Ok so over the last week after feeling pretty good on holiday I have started to feel more and more anxious and the last couple of nights my sleep has been about 6 hours.

I know it's a very slim chance, but could this be withdrawal from the propanolol? I know it's probably not, and I know I'm just trying to justify why I'm feeling so crap.
