I've been taking clonidine for blushing for about 10 years now (50 micrograms twice a day) with absolutely no side effects... until now. All of a sudden I am really drowsy/drained and have to sleep for about 2 hours in the middle of the day! I can't do this most days due to being at work and so it just makes me feel really tired and irritable and it's affecting my performance at work. I have two questions re. this - why have I all of a sudden started to get side effects after years of nothing, and are there any other medications out there that I could try that cure blushing? As clonidine is the only one I've come across so far. Many thanks
