Forgot to eat before my antibiotics. help! :( urgent!

[♥Lizzie]

So just over an hour ago, I took my antibiotics. Then just a few minutes ago i realized I hadn't eaten anything with my antibiotics! I'm on Keflex (Cephalexin) btw.
Anyways I immediately got a wave of nausea (which is probably anxiety related?) and quickly buttered up some bread and ate that as well as a very small bowl of cereal - I still feel slightly sick! Not sure why Is it anxiety-related or is it from taking the antibiotics on an empty stomach?
How long until the bread gets to my stomach? was that enough food? Will I be okay now that I've eaten? HELP PLEASE

The bread will be in your stomach instantly. Don't worry about a thing. Cephalexin is actually very well tolerated and can even be taken without food. Doug
