My Doctor switched me from 40mg citalopram to 15mg mirtazapine a week ago - just switching without any overlap period. This was to improve my sleep and appetite. I took citalopram for 2 years.
For the first day I felt tranquilised and "nice", but since then things have gone downhill. Sleep and appetite have not improved. I feel faint and tired in the evenings and generally unwell, last night a woke up shivering in the night, and I feel tearful.
Anyone else have experiences switching between these drugs?
