It would appear I am a text book case having read your extract above (thanks for that x)
It is indeed around the 3 hour mark I feel a bit dizzy, although it is transient.
I went back to taking them in the evening, and had no problems.
As a test, I took one yesterday at about 5pm, and sure enough round about 8pm I felt a bit swooshy for a few minutes. Am satisfied now that its nothing to worry about

By the way - I am declaring utrogestan a wonder drug!

Awful awful bleak times on other progs, so much that I was considering foregoing prog altogether my symptoms were SOOOOOO bad...
Now I can protect myself by taking the required progesterone that my body needs, and feel fine whilst doing it!

So very very grateful for finding this site and learning that utrogestan exists - and for all the brilliant supportive advice I've had while going through the bad times on the synthetic progs!!!
