Oh, in addition to the antihistamines and relative to muscle weakness I hired a trainer to work with me on resistance training. After about six sessions with him I now workout from two to three times per week for a good hour - working on upper and lower body. What I did not know about resistance training and all the machines at the fitness center would have filled a book!

In addition I consulted with a PhD Biochemist, Clinical Nutritionist who has me on a number of supplements. He also recommended I speak with my trainer to get what would be as much of a total body workout in 10 minutes as possible two to three times per day. I use a 10 lbs. medicine ball and and elastic cord with handles for five different exercises. The nutritionist advised that within the first 10 minutes after the workout I should eat a small amount of dried fruit for a high sucrose dose (three or so dried dates, cherries or apricots) and follow it with 4 ounces of liquid protein. He said the exercised muscles will up take those nutrients and actually strengthen. I'm 79 YO and am now in some of the best shape ever. Also lost 20 lbs. Good luck!
