I know how you feel. I've been fighting a cold all last week and when I finally went to the Dr. on Monday I have strep. I haven't worked out in about a week. When I started feeling better on Wednesday I tried getting back on my Gazelle I started coughing like crazy.
My stomach muscles are killing me from coughing so much. I'm going to try getting back on my gazelle again this weekend. I've been sticking to my diet though so I don't gain any weight. I've been lucky I didn't have the monsterous throat pain like I had the last time. Hope you feel better.
