Has anyone else had issues with Centrum multi vits? I can't figure out why it gives me a bloated belly and gas for hours after I take it. There isn't any lactose in it that I can tell (old eyes don't read the small print well) and there isn't anything else that I can see that would set my gut off like that. Darn, spent good money on something I can't even tolerate. Oh and I'm not flaring by any means.
