Yes I'm pleased to say fizzy water has definitely got me through my night shifts, I have managed to drink 2ltr each night, I found it also keeps the horrible tastes lingering in my mouth, which I get both from the diet and from doing nights. I physically cannot stomach plain water all day and all night so it feels like a little treat, I sometimes drink it from a wine glass with a meal too.
I was just wondering if anyone else had had very strong cravings, mine are that bad I can physically taste the food, most of it is spicy food such as curry, chilli con carne and garlic too, but the first day was Greek chicken burgers (which I haven't had for 16 years!!!!) I'm finding it really strange, I don't feel that I want to eat them but I just get the taste which lasts a short while?
