It's hard waiting to get started but rest assured that in chronic phase CML is a pretty slow moving thing so the biggest problem is that these guys are messing with you. I did two IVF cycles before starting (to store younger embryos) so I had my first tablets sitting on the bench staring me out for over a month. They drove me mad but in the end the first pill was just a swallow...even after that it took 1-2 weeks for the side effects to really get started.
I was only a little bit fatigued at dx so the fatigue that came with gleevec was something else. Certainly a lot of people talk about fatigue with tasigna but it might not be worse than what you have now. Certainly I have had to accept that there will be days or more generally blocks of time in days when I can't function. Generally it is worst in the first 6 months. For me it was the kind of fatigue I couldn't fight, and believe me as a middle distance runner I fight fatigue better than most. Sometimes I just had to rest.
If you are exhausted now, rest, sleep. CML is not the common cold...it's ok to be tired.
Having said all that we've been renovating ever since dx...a completely crazy idea. We are doing up our small flat with large garden so that we can sell it and move into the inner city. We did hope to have it on the market about 6 months ago but things have gone slower than expected...some of that is me only being able to work about half as much as before but the bigger problem is that I'm married to a perfectionist. I was only this morning looking at the bathroom window frames which I stripped, filled and undercoated (yes yet to be finished) right at the peak of my fatigue, not a hard job but I sure remember having to lie down a few times. Don't forget to take before and after photos.
