I use it that way Angelcakes, but I am post meno. I didn't do too well on it for the first few months 5 is probably about right with depressive symptoms and a bit of cramping and feeling "hormonal", now I am at month 8 and it has settled. I do use a longer cycle through I go 4 weeks on oestrogen only and 10 days 200mg vaginally and the I get a bleed. Utrogestan is the best one I have used and I have tried a few over years, but you could be right, it could be too much progesterone, rather than intolerance because you have your own because you are still in peri. I have heard tell of 100mg vaginally being sufficient because it is more effective vaginally than orally when it goes through the stomach and the liver in the digestion process. Maybe Hurdity or one of the other ladies will comment on that especially as you are producing your own progesterone. Mayeb that would be enough?
Unfortunately I can't help other than what I have said, I had a terrible time on Provera, so it would seem again, as with all things, meno, it really depends on how your body reacts. Maybe try and hold out another couple of months if you can and see if it stops, if you can? I know that is hard when you feel bad but maybe you are nearly there and it would be a shame to give up before you found out if it settled?
