Hi, John -
Let's see, for starters, his energy level improved: he was able start riding his horse again. The increased physical activity helped his brain chemistry and let him feel better emotionally. When he started, I would tack up his horse, he would ride for aabout 20 minutes, and then get off - exhausted. He would rest and I would put up his horse. Basically, he would push himself a bit, and then rest to recover.
His eating slowly improved - we started adding baby cereals to his protein shakes little by little to add something that would stick to his ribs and be sustaining. We also began to add whey powder for extra protein, which I would highly recommend.
Slow but steady wins the race!
