the side effects of chemo can be awful. i had no energy at all, i slept for 4 days at one point and it makes you throw up too. i had severe back ache and a headache that strong you couldn't even imagine it. my mouth and throat was full of blisters and my nose bled constantly as i had no blood cells to clot the blood. many people don't realise what chemo actually is until they experience it, i didn't even know how it was given or anything but people on chemo deserve blue badges as much as anybody.
