Any suggestions??
What is the sugar level (carbs) in the items you are drinking? I know that unless you have found the sugar free Carnation Instant Breakfast, it is very high. You might me having a sugar reaction, not just a lactose intolerance.
I have somewhat of a similar situation. When I get up inthe morning and start drinking ANYTHING, I end up at the potty in about 1/2 hour. Since I mostly drink flavored waters, I can tell you that it is purely based upon fluid, not lactose or sugar.
