Hang in there, folks. My motto during treatment was, "Whatever it takes." Life is worth the investment. No matter how crappy you may feel on any given day, it WILL get better. I felt icky for a day or two out of each cycle, never quite GREAT, but only a few bad days each cycle. Everyone is different. But when it's over and he's unhooked for good, it will feel SOOO good! And as Mark's strength comes back it will all be worth it.
