I've used about 3/4 of my first bottle after 2-1/2 months, but once I got it cleared up, I usually only use it at night unless I'm having a little flare-up. Like you, I don't use it sparingly when I use it since I want its full effect.
I'd probably use it morning and night if I didn't have seborrheic dermatitis - when I used it twice a day regularly, I eventually had a little cracking and flaking in my nose creases which made me cut back on it some. A little too much alcohol and acids, I guess.
