Yeah, 40 pounds is a lot. Tell me about it. I'm glad that this is not in my head and that there could be a real reason for all of this. Honestly, my doctor is a guy, and I can't help but think that may have something to do with it. I've been thinking about finding a new GP, my other one was great, but when I mentioned something about my libido taking a nosedive, he seemed a little uncomfortable and changed the subject. Thanks again for the help, ladies. I'll do some more research. If anyone can think of anything else to help, let me know.
