Hi there, Late last year I started suffering with anxiety and between my Dr and a physcologist they prescribed me mirtazapine. My anxiety has settled down considerably but my weight has increased considerably, so the other day my gp prescribed duromine. I have read in places that duromine causes a range of side effects including sleeplessness. Does the mirtazapine help with that sleeplessness that the duromine may cause and are the side effects of the duromine long lasting or usually only in the first few days ?
