Ill on first date?

I've got a cold. I sneeze literally every 2 minutes and it's gross. Disgusting. I'm working my way through toilet roll just by blowing my nose. Sexy right? Well a guy has asked me on a date tomorrow. It'd be our first date but I don't know if I wanna go while I'm sneezing all the time. Should I just tell him I'll be sneezing constantly and he might catch it. Have you ever gone on a first date while ill? Thing is I won't be my normal self I'll be ill, tired, groggy, out of my head and bunged up. So idk what to do
