For women who had RNY and are on HRT

I am wondering if anyone has had good luck with any hormone replacement therapy, preferably a natural treatment.  I currently use an estrogen patch, but am not getting the best results.  I can't take normal HRT because it's all time released, and that doesn't work when you've had RNY.

I am considering WLS and which one and looking at the RNY.  I am  also am on a patch.  Why won't the time released patches work with RNY?  Is that all time  released medicines? 

Actually the patch is the way the dr's recommend for WLS patients.  I need to find another thing to do because I lost my health ins and can't afford the patches anymore...just didn't want to put that in the intial post .
