Thanks for your support. I am just going to concentrate on getting through my work week and do nothing else. As soon as I get home I am going to rest, and tonight I am having a hot bath to try and lift the fatigue and have an early night. I was due in for 4 days the following week with two 8-5 days, but depending on how I get on I might have to cut back. I have an understanding employer and good colleagues so this helps.
