Fruit make anyone else's stomach feel bad if eaten as breakfast?

[samy23]

I started having fruit as part of my breakfast, and it seems to make my stomach feel bad....why is that? Anyone else experienced this? Is fruit not a good breakfast food for some reason?

So far I've asked 2 other people about this, and they said they experience the same thing.

It did, until I stopped drinking coffee a couple of months ago. Now it seems to be fine.

There are people who subscribe the whole food-combining idea which instructs that fruit should always been eaten separately from any other kind of food, and often not mixed with other fruits. I obviously don't follow this rule myself, since I've been drinking smoothies made with multiple fruits, milk, yogurt, flax seed, and maple syrup, and my stomach has been fine.
