I know a thing or two about addiction my friend and like u said at the end, u dont have much to worry about here..
I would like to tell u that i personally dont think moving to 2 fingers on each hand will hurt u more than help u. That means u will have to relearn how to type 4 more time before u learn the "real way".. my advice to u is to practice for 15 mins each day the real way! Put all ur fingers on the keyboard and go thru the abc's until u learn them, then move on to small sentences.. it will be painfully hard at first, but much like steemit u will be doing much better in a few months.. and definitely saving quite a bit of time by 6months.. just a thought from a crazy hippie 😉
Hope u have a great day!
