Mixing IO, IH, IG and TUTH: do sprays of different products add up to an overdose?

I second what he just said. Try reading this: How to find your sweet spot...

I know it’s incredibly hard to resist getting started in a way that seems faster, but trust me (I tried to start with combos), it’s in the end faster to figure them out like that ^^. Just in case you can’t resist temptation there’s more than enough info to help you be fine and not waste so much time, but if you have an ounce of patience, I STRONGLY recommend you use every last drop (and spray and microgram while you’re at it lol) to take your time and do it right, eventually you’ll come back to doing it that way anyways…

Either way though, nobody will think less of you if you don’t (most people jump right in, I did really badly) and I hope you the very best of luck!!!
