You're not impatient - you're just hitting the wall where vanilla Skyrim's progression stops mattering. The restoration loop does work, but yeah, it's kind of a trap for completionists and people who want to optimize before they actually need to.
Here's the real talk: by level 19, you're already past the point where it would help. The loop is only "worth it" if you're building towards something specific - like you want to craft a set of gear with insane enchantments before tackling Legendary difficulty, or you're trying to hit a damage cap for a challenge run. If you're just playing through the story on normal, you'll trivialize content whether you do the loop or not.
The grind itself is tedious because you're literally just making the same potion 50 times while watching your stamina drain. It's not fun, it's just... sitting there. And then you make one enchantment that's marginally better than what you already have, and the dopamine wears off fast.
My take: skip it unless you're specifically planning a build where you need it. Invest those three hours into actually playing instead - do a faction questline, explore a new area, work on perks you actually want. The game's already easy enough that vanilla gear and a decent perk spread will carry you through everything. The loop rewards obsessive planning, not good gameplay.
If you do want to min-max, there are less tedious ways - just grab better perks, use standing stones strategically, or farm better loot. Way more fun than alchemy grinding.
