I was feeling spontanious last week, so i walked in and got my rook done :D
The piercer reccomended that do the SSS in a drinking bottle with a pump top. I just cover my ear hole with my other hand and squeeze a decent amount of the water on to it. I tilt my head a little and let it sit for a few secs. But it seems to be working quite well. Sleeping sucks though, because i always sleep on the right side, which is the side i got it on D:U
anyways, give the bottle a try! its a little messy but if you do it morning/night its refreshing :D ahaha.
good luck!
