DONT Take more!! It's affecting you more than u think, in fact don't dose that 2morro, what u took today is still going to be affecting yr breathing tomorow. I had the same tolerance as you when I started fuckin with it, you are feeling that 25mg more than you think! That was my dose when I took it, I use to get the 40mg wafers and would take 25, one time I did take the 15mg later into the next day, my breathing was really slow and I was just drowsy, but not in a fun way, the kinda way where I was scared to go to sleep. Save it for day after 2morro. Done is not as euphoric as oxy, so dnt let that fool you and take more. And yr only taking 45mg, plz dnt take more. And take it from sum1 with experience, the shit will RAISE yr tolerance!!! Tread carefully or better yet dnt until u actually need done', which I hope u dnt
