Hows it going 
For the past two years I've been taking hydrocodone about once every two or three weeks. Throughout this time I've taken a few month or two long breaks. I find it curious that despite this, my tolerance seems to be very high and not decreasing. Originally, just 5 - 10 mg would be like heaven for around two hours... but now 30 mg, even after 1.5 month break and on an empty stomach is just a decent experience only lasting about 35 or so minutes. What do?
