I use monthlies for my contact lens prescription and I find these really convenient. The only difference you'll have between what you've been doing previously and now is that instead of throwing your contact lenses away, you'll clean them in a solution and store them overnight. It's straightforward and easy to do and provided you clean them thoroughly with the solution and store them in the solution, you're fine. I've had mine now for over a year and haven't had any problems with them.
