Bejoi,
First of all, I wish you all the best tomorrow!
I haven't heard of anyone having nausea and i didn't myself either, but I have a little confession... I took a gravol before I left home mostly because someone drove me each day and I would be sitting in the back of the car often ... I knew from when I was very young and from things like boats and airplanes as an adult that I um had some motion sickness problems generally so i took the gravol for that not the fsr....
but really, I honestly haven't heard of anyone saying they had nausea from fsr and on the days i sat in the front seat (different driver lol) on the way there or back i didn't bother with the gravol at all....
fatigue can go hand in hand with simply having any kind of a brain tumour really, but if you are generally in good health regarding other things and working too, I'd guess that yours might be minimal.... or none at all, really....
I do at this moment recall being quite happy and "normal" after my first fsr treatment (and let's face it, it's a new experience and one doesn't quite know what to expect other than from what one has heard or read so it's tiring simply from "nerves" maybe) and then the only thing was that as I waited for my ride and discussed where to have dinner in a restaurant downtown with a friend who had also come to be with me the first day, I did get hit by a wave of tiredness and decided to go straight home... but again that was close to the dinner hour not like in the middle of the day etc....
fsr is also various lengths of days in treatment depending on the machine and treatment protocol so for someone having 3 days of treatment they may notice no fatigue at all during it, and for someone who is having 25 days, along with other variables such as how long it takes to get there, what the daily schedule re work and so on is anyway, and oh all sorts of things that tire people out regardless of something like An treatment, well, fsr itself during the treatment may not cause any fatigue? I recall being quite up and fine , in fact very buoyant emotionally, but then getting fatigued because of a long ride home (rush hour and winter) and often stopping half way to have a break from traffic of all things and having this really nice meal in a nice restaurant lol....
I know some people switched to half days at work because let's face it, with 25 days it eats up a lot of time... then again the 3 day ck fsr is so short it's more like little blips on your personal life screen ....
if You are tired i'd say listen to it and rest as you need to.....
thumbs up for tomorrow!
