It took me about three weeks to learn Colemak. I practiced with keybr.com but Klavaro is also good. It was not easy to switch back and forth to qwerty, I forgot how to touch type with qwerty. If you are going to need to switch to qwerty often and you already type at 130 WPM I would not recommend learning another layout.
