Hey Markus
The RO stopped me at 28 for a 2 week break (I actually completed 35) and sounds like you're in better shape that what I was at that point. Count your blessings. Everyone reacts and responds a little differently. There were 4 of us at the Cancer Center here going through the same protocol at the same time, and the results and reactions were different for each one of us.
Don't feel guilty, just smile!
