I never really had any trouble with nails. I got them for formals in high school, then on and off for a few years. At one point I had nails for over a year. Now I haven't had them for almost 2 years. You will adjust very quickly! The hardest part was the contacts, and I managed to get them out on the first try. Putting them back in took a little more effort, but no poked eyeballs!
My real nails don't grow. They are super thin, and break and peel easily. Toenails too. Doctor had me try all sorts of stuff to help, but nothing helped. My nails are just destined to be thin and break. I wish I could get fake ones again, but I just don't have any money.
