I found a useful site you may want to check out...http://www.cancer.gov/cancertopics/coping/chemotherapy-and-you/page5 As you probably know, fatigue is a major side effect of chemotherapy. Fortunately the health care providers have the side effects pretty well managed preventatively with a variety of medications and it sounds like they are working pretty well. The only medication that Andy is taking that causes the double vision is the Ativan, and the dose may need to be adjusted to remedy that. I hope that all the rest he is getting will help the drugs fight these cancer cells successfully. Happy Birthday to Scarlett! Happy Easter to all!
