Here are the things I tried each worked well for a short period of time in order from week 6 til the 41!
Barley sugar constantly sucking on one the whole time I was awake
Milk - bizarre but true it worked for about a month
Choc chiller ice thing from Gloria jeans!
Salt and vinegar chips
Chewing gum - the blue extra brand I chewed constantly
Then the last month nothing worked and I was on a drip when it got very bad.
Ginger didn't work but chewing gum was the most effective
Hugs it's awful and makes you give dirty looks to glowing mummas!
