Hmmm, Gypsy, not sure what that could be. Lactose intolerance does not usually start in adulthood. Any problems with allergies or digestion prior to this? If I may ask what did you eat eight hours or so before you felt unwell?

It could be poor liver function which leads to poor digestion and can build up into something painful. Try what I was saying to JBH about the lemon juice and veg juice every morning and then go non-dairy (including egg yolks) and vegetarian for two months. Then you'll give your liver a good old cleanout and your digestion should improve. Drink lots and lots of water and reduce caffeine to a minimum. No booze or ciggies either.
