My MIL has taken 10 rounds of the chemo Temodar and yes she is very tired for atleast a week after ending the meds. Some times it is very bad and she doesn't feel well until a week before she starts her next round! We have learned to take everyday that she feels well and make the best of it. The week before she starts chemo we have her over for dinner and get her out to the park and things she enjoys.
I see you posted under after treatment...you may get more responses if you post under "brain cancer."
Hang in there and keep us updated.
