Let my soil dry out, gnat's aren't there anymore, plants drooping

Water it a bit with hydrogen peroxide to kill off any larvae in there. Managed to not see any gnats, but the plant is awfully droopy. I heard its normal when it drys out to droop, but I just wanna know if it'll pick back up soon.

Yes, assuming that is the gig it will be fine. Sit back and watch, you can actually (albeit slowly) watch the leaves start moving real time after you water.

Noticed the leaves 'bouncing' a bit, looks like this is a good thing

Ok.. step farther.. see how you read those leaves? You communicated with your plant.. you understood it was thirsty..

From now on, read the laves when watering.. they will tell you when to water ALWAYS.. never let them get droopy, but just the onset of the bigger bottom leaves just barely starting to droop and lose a bit of elasticity, that is the PERFECT time to water and your plant will tell you so just 2-3 minutes afterwards.. Read the leaves DAILY, your plant will tell you what it needs long before it needs it ALWAYS.. most important advice I could ever give.. you just started doing it today.. good on ya.
