For me I drink gassy drinks so that I can burp and I did went to GP to get gastric medication. I have gastric even before pregnancy. Anyway, after consuming medication and once my tummy feel better, Ill eat in small portion and drink plain water after that. I dont lay down straight away as that causes bloating tummy and acid reflux. I dont skip meals on the morning, have something light and milk to ensure I dont get gastric too.
