You must have bought a big box store brand softener. They are the only ones that call for less than a minimum 1/2" ID drain line (which is industry standard).
I would not run a 3/8" anywhere near that far, I would use 1/2" at least. Control valves that I sell I use 1/2" up 6-7' above the control valve and then sideways 20-30' and 40' if you bring the drain line back down.
If you get this wrong the softener wil not work right very long.
And use PE, not vinyl that will kink closed just from its weight.
