essentially what i did was do drills
for at least like 15-30 mins a day i'd just practice the motions
I'd do like 10 consecutive 623's, then do the same on the other side, then 10 236's and another 10 in the opposite side, 10 632146's on one side, etc....
then after drills i did combo training, working on one combo a day
I got consistent in like a week to two weeks of use
Its funny though, whenever you see me in public now and i sit down, i have my hands in a position holding a joystick. Sometimes you'll even see me do the motions out of nowhere when walking, sitting, etc...
