Should be getting my medical back....but...

Looking for some advise here. I have been sitting on the sidelines
for about a year now after discovering that I have sleep apnea. I
never failed the failed the medical, but just didn't go in for the
test because I has not treated my condition. Now I have and I've
never felt better!

The question is...what exactly do I need to get my medical. I have
been to the AOPA web site and I can't figure out if I need a MWT test
ot not.

In paragraph 1 it says maybe not. It paragraph 2 it says every year
for the rest of your life! Anyone have recent experience with this?
