I had a mega craving for lucozade for a couple of weeks in 1st tri, and as i wasn't able to eat much i gave in and drank it. Usually i hate fizzy drinks! Even since then i've had a craving for fizzy!
What i did was pour about an inch of lucozade into a tall tumbler glass, and top up with fizzy water! Same taste, craving satisfied, less sugar! Now that the lucozade craving has gone but i still want fizz, I get a good squeezed orange juice and top that up with fizzy water! Works a treat!!
