I did something like this once and I was a mess all day. Way too much to cover it up and go to a party! I think the extra dose will make you feel weird and sedated but it is probably ok for you to be alone. I would just stay home if I were you. But I can't tell how freaky it is and how much is just sedation. If you're pretty freaked then you should have your family stay home with you. Maybe just say you all have a virus.
