Benzos methadone and klonopin?

[pahn]

hi all. been on methadone maintenance at 60mg for bout 4months. i use benzos every once in a while for my anxiety (and for a lil benzo high here and there). My doc is DEFINITELY xanax, because ativan and klonopin dont seem to do ANYTHING for me even with fatal doses. I recall taking 7mg+ on top of my done dose before, and felt NO effect, but i could be mistaken. In any case, i went out on a xany bar hunt and came up with 1mg kpins the round blue ones, and i popped 5 of them. this is 12 hours after my 60mg done dose mind you. after dosing this i stumble across a few bl posts saying how deadly this can be and its scaring the shit outta me...its only been a half hour since i popped em so i havent felt ANY effects yet, but as i said i recall taking doses much higher than this and feeling nothing! my average xanax dose is about 4-6mg, sometimes more!!! should i be concerned? any help would be greatly appreciated. Ive managed to build up a benzo tolerance over the past few months, so i think i'll be ok for the most part.
