Speaking of which, I spent the night with a guy too, but he is the only one, and we were serious by then, but he is now my husband, lol. Anyway, back in those days, I DID sleep with my contacts in all the time. Now that I am married to him, I take them out at night and keep the solution right by the bed. BTW, I have severe dry eye now, and the doc says it was made worse by wearing contacts at night. If I knew then what I know now, I would have had the solution ready in the lens case, and slipped the contacts off once the lights were out, then slipped them back in first thing in the a.m., so as not to blow my cover, lol. So once in a while, it's okay, but don't do it on a regular basis. And always keep rewetting drops handy.
