Nasal spray...is it worth it?

If you can get a theoretical max of 200mg/ml in a spray bottle (so probably 175mg max) how are you not drinking the stuff?

I don't use ketamine much, because I'm terrified to lose the magic. It takes me about 80-100mg insufflated and some music to go to other places and genuinely have an awesome (albeit short, but I ain't IM'ing) session that blows my mind.

I wanted to make some spray, but it outputs .1ml per spray. I'd have to do 5 sprays to get to 87.5. is this doable? Seems like a lot of spraying.
