oh my goodness. last night i was trying to fall asleep, and my left ear kept ringing. i hadn't really noticed this before. last night was my day 5 of my temodar cycle. i have now finished my 6th cycle. this time was the first time i had noticeable side effects. i have been really tired, upset stomach to the point where i havent wanted to eat as much as usual, itching, and then the ringing in the ear last night. i am not on a trial, but i know that there are some here at UCSF. wishing you the best.
