Pregnancy hunger pangs....

OMG, the pregnancy hunger pangs have started! Real burning, acidy kind of feeling (to the point where I wondered if it could be gastritis, but I do not really have any other symptoms). I am SO hungry I could eat everything in the fridge, despite having had two dinners and snacks!

Does anyone else get this and have any helpful tips?? I don't want to not eat if I am really hungry, but need tips for things to help me feel fuller for longer.
