In 814 patients randomly allocated to fish oils for 18 weeks for the reduction of re-stenosis after percutaneous transluminal coronary angioplasty, gastrointestinal adverse effects, most commonly bloating and burping, were reported in 37% of patients taking fish oils, versus 31% of those taking placebo (13). 

The re-stabilizing of the stomach pH can be helped by taking stomach powders Rennies , Alkaseltzer or small amounts of bicarbonate of soda , etc. These materials add a small amount of basic OH ions or bicarbonate, HC03, ions in order to react with the excess acid. Unfortunately the bicarbonate ions produce C02 gas which causes you to burp. 

The second thing to remember is that a cut on paper may not work on film. The way people speak often reads differently than it sounds. People end sentences with a question, or they run two sentences together, or they burp or sigh, or a plane flies overhead, or their energy level shifts so much that you can t cut between two bites. You do the best you can to note the big issues when you re watching rushes (the raw footage) with the transcripts in hand, but there will still be times when something that should work just doesn t.
