Yeah, I'd definitely call. You just never know what he/she might say. (Sorry, I don't know who Dr M is, lol.)
As for Dr W, well, I don't think he can tell you to stop with a new DE cycle, can he? I mean, he can advise against it all he likes if he thinks it's not going to work, but he can't really stop you!
And hell, if he does try and get in your way, I'm sure another of your Doctors could guide you through the process?
Hugs to you hon. I know that hopeless feeling too bl00dy well myself. Just remember the sun will shine after every storm
