I did not have any problems with my memory. The tumor was on my occipital lobe, which controls vision. I was on Temodar for 5days a week and than would get three weeks off, and we continued this schedule for six months. During radiation I was 120 mg of Temodar and than they upped it to 260mg. I had a hard time with the big dose. The first month they tried it, by the fourth day I was throwing up the pills. Than by day five I was throwing up so much I had to go in for IV fluids. Than I had over a month off because I had another surgery. When they started back up again I was very sick from the Temodar. I was throwing up everything and had to go back in for IV fluids. Thats is when they reduced the dose to 200mgs. Than I was ok. I was very tired and lost my appetite when on the Temodar. Certain things I could not eat or drink. We stopped the Temodar after six months because I am only 26 and my doctor was not sure if it would hurt my fertility. When I was on Decadron I had a lot of side effects. I could sit for very long, I was not sleeping very well, and I gained a lot of weight. I always felt hungry and thirsty. Right now off of everything I feel like a normal person. I am a teacher and worked a lot of the year. I missed 6 weeks for my surgeries, I left early everyday for radiation, and missed days when I was sick on chemo. The other days I went to work, but it was not always easy.I hope this helps. I am sure it is tough but just keep on hoping.
