I went to see my GP this morning and it's been suggested I change from sertraline to mirtazapine. The sertraline is great for my moods but I can't orgasm on them - even at 50 mg I could never orgasm and it's getting really frustrating for me and for DP. Doc suggested changing to something else and has given me mirtazapine, so for the next two weeks I've got to drop sertraline from 100 mg to 50 mg and can then start taking the mirtazapine. Am I bit worried about taking the new on though and so wondering if any of you have any experience with it?
