Came in here last month, happened to be the happy hour special the time we arrived, so we gave our first try. It was fine but I didn't feel much difference after this, my mind was telling me I should feel better since I'm getting some fresh oxygen. Whatever.
My nose bleed the next day, but I heard it happened to some people as well. So that's fine.
I wouldn't mind doing it again next Time even I didn't feel anything this time, as long as it's not doing any bad to the body, why not?!
