All four of my characters take enchanting, and two of them also use smithing. I'm at 299 hours this morning.
But for none of them, am I powerleveling any skill. Every so often, I do a little enchanting and smithing and then let it go for 4-5 (real life) days, before doing some more.
I want this game to last a while, and had read about smithing, enchanting, and alchemy early on, so I decided not to power level them.
I find that if you don't farm, grind, or overuse vendors (like traveling from town to town for mats, or waiting whatever amount of hours for them to restock, ect.), blacksmithing levels at a pretty reasonable rate with just "found" bars and ore, and looted leather.
Doing something similar with enchanting. I make sure to enchant any rings, necklaces, ect. that drops off of enemies before I sell them, but haven't put a dedicated effort into the professon. Still, already have it in the low 70s with no perks assigned.
