@sallyo420 thank you for replying. Yes the GP was pretty short in response but clear to have recorded it was my decision and against medical advice! He said no point in tapering any further.
I was on Prozac about 10 years ago and it was okay but since then I had an infarction of brain results in mild tremors of mouth and thumbs. Citalopram trial was awful - tremors increased and felt very anxious so stopped after a week. So ssris may not be good for me now. I have been off the Mirtazipine two nights now and the burning skin sensation was not as bad this morning so will see how I go.
Mirtazipine is a very sedative drug and good for sleep but I dread to think what it is doing to brain in long term!
