I've started to get them as well & they are just horrible.

When I was pregnant with Zander my Dr recommended having a little bottle of tonic water each night with dinner to help prevent them. There is quinine in the tonic water & for some reason it helps. I couldn't stand the taste of it even mixing with something else, so hunted for something else, I found Schweppes Bitter Lemon in the little bottles has quinine as well & they taste waaaay better. So maybe try having one of them with dinner each night & see how you go.
