My daughter, Lauren, has been on many different chemos and they were all every 2 or 3 weeks, never every week. I think some people do get it weekly, but I think they would need a rest week in there. Lauren was never totally incapacitated while on chemo. Certain ones would make her very tired for a few days, but she would bounce back. She is in her 20's, so that might have something to do with it. Every chemo affects each person differently, so there really is no way to know how your dad will feel. I'm sure he will be happy to see you whether he feels good or not. Prayers for you and your family.
My beautiful daughter, Lauren Patrice, will live on in my heart forever.
