Is it true eating bread before drinking helps prevent your stomach from rejecting everything?

I usually just drink alot of water all day and usually helps my stomach later on when I start drinking, but I got sick last time so my friend told me to eat alot of bread tommorow before my other friends party. Just wondering if it truly helps. I think I just got sick last time because I drank on an empty stomach... show more I usually just drink alot of water all day and usually helps my stomach later on when I start drinking, but I got sick last time so my friend told me to eat alot of bread tommorow before my other friends party.
