Hey Flan,
I have been on the evorel 75 for a good 2 years now (give or take 3 months on femeston conti 1/5 ).
I think anything is worth a try, but do it slowly. I don't think the body likes too much of an increase all at once.
The trouble with estradot, is that they are so small, so hard to cut them down to any size I guess.
I tried adding a half sachet of sandrena to the 75, but that didn't do alot. I don't think the patches are being absorbed properly, that's the issue. I am now trying sandrena on its own (not holding out much hope for that either!)
Good luck with the health kick, I hope it works. x
