I've been using klonopin almost daily, for...hmm..around 5-6 months maybe? I stick to around 4mg/day, although sometimes 2mg, sometimes up to 6mg. Sometimes none at all. I haven't gone long enough without any to notice any withdrawl yet (well i did go to florida for a week, which i barely used any at all, maybe only 2 or 3 2mg pills during the whole week, didnt notice any extra anxiety) , but i think i'm going to slowly ween down, since my main CHEAP overseas suppliers are all not operating, although i made sure to have a years worth of "stash", so i wouldn't have to quit cold turkey. Try cutting down the dose little by little, that is if you have enough left to do that with.. I think there are some posts about this in Medical Q&A.
I take them for anxiety, which with the US doctors, its so much of a pain to get them, and its still cheaper buying 400-500 2mg pills overseas (well, my main cheapo suppliers are gone now) for about $90 including shipping. Cheaper than wasting time going many doctors, with most of them telling you "here's some paxil, here try some of these other anti depressants", If i had 100% coverage insurance, maybe i would try and waste the time, but it would probably be a LOT of time i dont have. Most of the doctor's i've talked to, have some ego-thing going on, where they cant seem to believe I read up and understand what these meds do, and i'm aware of the withdrawl/side effects/etc.
After using klonopin for so long, i've built up a tolerance for sure, but it seems to have reached a plateau, a long time ago. When I first tried it, it seemed to mess up my coordination, i would almost bump into walls at just 2mg. Now it just kills my anxiety, but no longer makes me sleepy, no longer fucks with my coordination, so i've probably just "adjusted" to the altered state, like someone who drives while high on pot very often, gets used to the changed state, and can drive fine.
Anyway, if you've only used it for 15 days (unless i mis-read the post, maybe you used it longer before then?), that doesn't seem long, compared to the 5-6 months i've been using it. If you have extra benzo's, i suggest you slowly (depending on how much you have) taper down. Come up with a schedule for reducing your dosage every x days (search medical q&a, or elsewhere), and stick to it, if you need to go real slow and you have enough klonopin, then why not do so? If your having real difficulty with cold turkey..i'd taper off, as fast or slowly as you need.
Also i notice, now that i have a script for Adderal (also BZP works for me), Adderal seems to kill anxiety, and "calm me down" in a way, without taking any klonopin.
Sorry if i'm ranting, i'm on Adderal right now, i've got some cleaning up to do/car shit to work on, but i somehow end up on bluelight first
Good luck quale.
