Clint,
It sounds like you are right on track to me. My fatique lasted well over a year. If you are still on pain meds that will make a difference when you stop those also. Vitamins don't really help much without the nutritional building blocks and if you can eat a healthy balanced diet many think that you don't need vitamins. Most of us did the junk calory thing just to have enough "fuel". I switched back to a healthy diet as soon as I was able. I never had a PEG so I had to rely on oral intake.
