Weight gain,muscle pain/tiredness especially in the lower legs. Fatigue/lack of energy, moodiness. Also intestinal bloating/gas. Getting adequate exercise is problematic given I can't get my heart rate into my target area, and the almost constant pain and dead feeling in my lower legs. It gets to the point that I have to stop walking and wait for the blood flow to reach my lower extremities. I am assuming this is a large contribting factor to my weight gain.
