I also went cold turkey a couple of years ago. The reason for me was that I experienced pain in my fingers after typing. After a day at work I was guaranteed to be in pain. At the time my productivity plummeted and it took me maybe two months to get to a level where I wasn't constantly frustrated.

That said, I've never regretted the switch. Even though I still feel pain sometimes when using a laptop keyboard the pain is mostly gone. Other benefits include that I've properly learned how to type and I am able to type without looking at the keyboard, something I could never do using QWERTY. I don't know if I write faster, but since the pain is gone I'm satisfied.

I suggest you stick with it. It will get easier and you won't regret it.
