It took me 4 weeks to get back to 50% speed. 4 months to get back to 75% speed. 4 years to type faster than Qwerty. I'm incredibly happy with my switch. I was getting RSI pain from awkward top-to-bottom row maneuvers with Qwerty. I still have some pain, but that's mostly from using the computer far too much. Most of the challenge is not about learning the new layout, but getting your muscle memory to forget about the old way of doing things. If I were to do it again, I'd recommend a progressive layout change; switching a single set of keys at a time. It takes longer to switch, but reduces the upfront mental load.
