Indigestion, Nausea and supplements for digestion

Hi! Currently in 2nd tri and have been throwing up more due to slow digestion/indigestion, which makes me nauseous also. Was prescribed Gastric pills (omeprazol) by KKH and they help a lot but was advised to also just take when necessary although I have found it helps if I take every day. Does anyone else face the same thing, and is it ok to take the gastric pills everyday? Also wondering if any mummies also take probiotic pills to help with digestion? Thx
