Hi scottishjune

Apparently Femseven patches are out of stock in many places because the manufacturers are improving the glue (as reported on this forum) - presumably this problem has been reported so many times?
Probably not a good idea to heat the patch directly with a hair-dryer because you could deactivate some of the oestrogen - better idea to warm your skin with the hairdryer. The Tegaderm seem to be recommended by some women on here but the main problem with these are - you can't really see if the patch underneath is stuck directly to the skin - which of course is crucial ie it may appear to be stuck fast but the middle might have come away.
Re application site - butt cheeks all the way! As long as you are not a thong or Brazilian gal, then if the nix cover the cheek it should stay put - just be careful when you go to the loo ( ie don't peel off your pants and jeans) and give it a warm palm every time you do so - to make sure it is still well stuck down - you should at least have a better chance...you'll get used to it! Hopefully the new formulation will be an improvement because many women seem to like this patch and not so much the Evorel conti/sequi.
(I've used Estradot patches for 10 years, which are tiny - and separate progesterone).
