Thanks for replies, as you say it'll be over soon. My approach has been just getting on with it no matter how bad it feels. Eat even if you don't want to, move around as much as you can, get fresh air, sleep if you can, drink plenty, i've gone off my beloved coffee, chocolate is nice now and again, lucozade cold is wonderful, small portions of food better as a plateful would feel a challenge. Cups of tea a must with 2 ginger biscuits for breakfast. It's all a bit weird but slowly working. Im going to halve the sleeping tab to start with as I'm a bit apprenensive.
