hey Sonia, thanks for sharing the proper breathing techniques - I'm going to start trying that right now!
Also, when I first started taking megace it had the same exact effects on me as you described. My appetite has been poor ever since I had my gallbladder removed 6 years ago so I now use Megace regularly. It IS a hormone, so if they do want you to take it long term, make sure you're aware of all the side-effects, etc. esp. pertaining to your CFRD.
I'm so glad things are finally on the up for you!! <img src="i/expressions/face-icon-small-happy.gif" border="0"> Scary about your PICC, but glad they figured it out (eventually *sigh*).
