Was diagnosed with MAC in January 2015. I have lost over 1/3 of my body weight (60lbs) in the last 6 mo. Infectious disease doc has not started me on anything yet other than Dronabinol to help me gain weight. It's not working. I have no energy and no appetite whatsoever. I am drinking Ensure+ everyday. We are taking cultures every other month. The show that I have MAC. I also am experiencing a lot of anxiety and my doc gave me 10mg of diazepam to take about an hr before bedtime. Also taking a strong sleeping pill. Still have problems falling and staying asleep. Any suggestions on how to gain weight and improve energy. REALLY NEED HELP with this. Also have PTSD.
