This is embarrasing... All of a sudden, I stink. Stinky underams, really stinky feet!

I've never had this problem before. Within 10 months of becoming post meno, this body odor problem has started. I started having profuse sweating along with the hot flashes, and even when I wasn't feeling hot, I was sweating. I started taking HRT. The vivelle dot, and prometrium. The sweating and hot flashes has stopped, but the body odor continues. I take a shower in the morning and a bath at night. I'm okay for a couple of hours, but then the odor returns. What in the world is going on!
I use an antibacterial soap, shower to shower powder, etc. I've had to throw away a several pairs of shoes, because they...Stink!
I never had this problem before, even in puberty. Anyone else dealing with this, and what did you do to cope with it?
Any help would be appreciated. {{hugs}}
