Hi Nads
I've just finished Chemo and start Radium in just over a week. I too work with children (teenagers!), originally I thought I'd be able to do both but my onchologist basically said 'no'... I'm glad she did. Even though Chemo wasn't that bad (yes Nausea) I found the fatigue the worst..I don't think I could of worked. There were days I found it difficult to get out of bed, let alone go to work, plan what I was doing and then have the energy to keep up with the kids. Day's 7 - 12 were the worst for me and the others I wasn't up to my usual energetic self. So definately consider plan B...
take care... and remember 18 weeks is such a short time in the scheme of things....
