I would suggest giving it a week or so off of one before you start the next. I wasn't on femoston, but after almost a year on patches and utrogestan I spiraled into a dark spell. When I stopped in January, I felt better and better each day before symptoms started to return, I think about 6 weeks in. I haven't yet gone back on anything. The worst of it seems to have passed and while I still have bad times, they aren't as bad and don't last as long as they did before. I am actually afraid my doctor is going to push me back onto hormones at my annual visit since I'm pof and need the estrogen, but after that dark dark spell, I'm terrified of trying hrt again.
