Hi,
I hope I'm not being too irritating by not really answering your question.
I, like some others, really struggle with utrogestan. I did find I had less side effects taking in internally. I was told by meno specialist that I could take 1 tablet vaginally for 12 days rather than 2 tablets orally.
My daughter is on sertraline (now on 50, started on 25) and apart from some initial nausea is doing really well on it. I didn't know it could be used sequentially, but please let us know how you get on x
