No, not really. Your eyes will get used to them, trust me. If they're bugging you tomorrow, wear your glasses on Friday, then practice putting them in this weekend. That's what I did, and I was pretty much a pro by Monday.

I would reccomend getting re-wetting drops and keeping them in your purse. These are eye drops that you can use with your contacts in. They come in handy if you get something in your eye or if you're going to have to wear them longer than you normally do (for instance, I use them if I go to a concert straight after work and I don't have time to go home and put my glasses on), they help with eye strain that can occur if you wear contacts longer than 12 hours.
