I've been on Dvorak for 4 months. First two weeks will be PITA and you'll lose your productivity at this point, so be careful about that. The most important thing is that you should forget about qwerty at all and don't make yourself switching to it. You must type on Dvorak even if you're very slow. There are a lot of online trainers you can use to learn how to properly type in Dvorak layout. After 2 weeks, you still will be slow but at least you can type something without a lot of troubles. After that, just do typing and you'll increase your wpm. I've printed a simple Dvorak keyboard layout because I were learning blind typing (I don't know the proper name of it, but the thing is that you type without looking at your keyboard) again and it was hard to me to remember new key positions. Don't forget about keybindings, they'd be changed too. I'm using dvorak-qwerty layout for that though, so when I press Ctrl, my keyboard uses qwerty layout. However, you can learn new keybindings if you want.

It's worth it and I don't have any problems using qwerty on other PCs. Not at the same speed as on Dvorak though.
