I was on escitalopram 5 mg then up to 10 mg then up to 20 mg.this I was on for 7 weeks knowing it could take 2 to 3 months to reach benefits .However doctor changed men's to mitrazipine 15 mg as he said I should be feeling some benefit on the escitralpram by now I was not sleeping and losing weight not that was a problem as I have weight problem. I am on day 3 of mitrazipine 15 mg slept well day 1 and 2 and felt a lift on day three not much sleep at all just drowsy all night am seeing doc on the 10th April for update .any help would be grateful.
