I had bad bloting for the first trimester and thought it had largely gone away. Now 23 weeks and its back. I've had enough and just wanted a bit of a rant! I don't understand it when people say they are eating like a horse because if I have even a small snack I'm full for the next 5 hours. I think I'd gladly swap it for sleepless nights right now! at least then I'll be able to eat without being in pain. grrrrrrr stupid hormones.
Have you tried mixing ground linseed into cereal etc? It isn't the nicest tasting stuff in the world, but it does soothe the gut, help prevent constipation and give you a big dose of omegas. I swear by it (and I have a really poor digestive system).
