Glad to read you are feeling a little bit better today. The weakness is normal for most people so don't get discouraged by this. Nutrition and hydration are number one and two and affect your body by assisting in repair. Protein shakes like Bart mentioned are great ways to supplement. I used Jevity in the tube several times a day and always closed out the day with any shake. The ice cream was cooling and soothing to a radiated throat. Keep up your spirits and put on your warrior face. We will coach and try to encourage you on your journey.
