(((Dvannie))) it's a very personal and tough decision to make. Whichever way you choose, we'll all be here for you! I find stairs the most tiring, but I do have a lot of them and can't avoid them anytime I'd like to go out, watch TV or do my laundry; pffft!
I'm sure you've read all the articles on MUA here and have also read the MUA stories from other members, so are fully aware of the pros and cons.
I may find myself in the same boat as you next week when I see my OS, but to date, he hasn't even mentioned it. If, at 11-12 weeks, I am still stuck with 85 degrees, I may seriously consider the idea. Time will tell.
