wow, who's your doctor Rush Limbaugh? Just kidding. So on the one hand 640 mg's a day, the equivelant of 8 oc 80's daily, is a high dosage, though I have heard of higher. On the other hand, 25 days is not a long time. You can and definetly should try to get off. I dont think its a bad idea to talk to your dosctor about how fast you tore through the script. After all, you didnt perscribe yourself. I do not think that going cold turkey would be life threatening, but I can bet it would be very uncomfortable. I definetly would reccomend a ween or a taper before jumping off to ease some wd. Please be sure to talk to someone who is an authority before taking major steps. Before being trully done with it, you must address the question of why you abused the script in the first place. Hopefully this is a one time slip for you. Just a warning, if you had purchased your drugs from the street, and not been perscribed, this one month binge would have cost you close to 15 thousand dollars. Its all fun and games till youre hooked for 500 bucks a day, then its just work.
