Possibly, you may be swallowing to much are when you drink liquids.
I have one patient who spent the day 'sipping' coffee, juice. While 'sipping', this was getting alot of air into the stomach, and by the end of the day they were having terrible gastro-intestinal bloating, cramping, burping, etc. Take care when drinking throughout the day. My patient has recovered very nicely with no need for meds.
