Yes I'm doing low carb. Started getting some chest pain a week ago. Dr thinks it's indigestion and asked me to take Prilosec and some gas pills for a while to see if it helps.Hmm ... can't say that I have but I also haven't needed to take Gas X or anything similar since eating LCHF. Are your carbs possibly too high? You may find that a lower carb amount eliminates the need for any gas pills.
