Oh thanks everyone. I did what the nurse said last night and ate slower and didn't lie down for 2 hours afterwards. When I went to bed I propped myself up for a bit and then laid down fully and I was quite good. I took two antacids after dinner, so I think heartburn must have been it, along with a bit of stress. Ate lunch slower today and felt good after lunch. I just thought it was too early for heartburn as I don't normally get it. I suppose anything and everything can happen during this time. Lucky us...

thanks again for all replying
