Francis Ann : Sounds like you're on the Vivelle Dot, which is also my favorite.

So tiny and convenient, and packaged to be changed every 3.5 days so they match what my endo wants me doing anyway.
I've never used anything but patches, but I've had fantastic results, so I'm happy with the method. I'm also so forgetful that even changing the patch twice a week means I have to set an alarm on my cell; I'd NEVER manage to remember pills 2X a day or more.
I also second that it's really important to clean where the patch goes, and wipe down with alcohol first. I was getting terrible rashes by not doing that; as soon as I started scrubbing the skin first, no rash anymore.
Not to mention that now that I'm post-op, it is really handy to be on a method common among menopausal women - I tell doctors that I'm in "surgical menopause" and using one of the standard Vivelle doses for it, and they have no problem understanding that and no awkward questions. (My regular GP knows the full story, but I don't see the need to get into it with eye doctors, allergists, etc. as long as they know the important bit : the medication and why.)
