Just skim read, but agreeing with a lot of what I read.
My own experiences:
Going off coffee, belching like a mating elk (so DP assured me!), acid reflux, leg cramps, throwing up when cleaning teeth, piles the size of melons coupled with constipation (not a good combination! )... but then feeling the baby move and all was good with the world. At least for five minutes until the acid hit again. my friends told me about Gaviscon but I didn't really believe them , until I took it. I had bottles in the bedroom, kitchen and living room, at my desk at work and in my handbag and happily admit to being a "gaviscon-aholic". Fabulous stuff!
