I've been doing it for about 6 months now. I've had several problems, but that is due to the fact I also suffer from Corneal Erosion, which more or less, is that my eyes don't tear at night. So they get REALLY dry, and it is easy for me to rip my out cornea layer. I have a pretty good eye doctor, and he managed to get some REALLY thin ones, that are wider than the normal ones, and this has helped me tons. I also put drops in everytime I wake up, just to make sure. And drinking causes some problems due to dehydration, but that's not really a problem, since I won't stop doing that! They are hard to get used to, but worth it. I take them out about 6 in the morning, and at 10 at night, I can still watch tv from across the room. My vision is better that 20-30, so I don't need anything to drive. They are light sensitive now, not terribly, but I squint a lot more now when outside. All in all, I think it was the best thing I've done.
