After having to have two cervical fusions in two months, I was on opana 20mg extended release and 5mg iR 6Xaday. I WAS TIRED OF FEELING SO TIRED N SLEEPY, SOULDN'T SAFELY DRIVE, AND HAVING RESPIRATORY DEPRESION AND STARTING A NEW JOB still feeling the pain anyway I wanted to try to get off it with suboxone. I've been on 12mgs over 24hr period now for over three weeks. As some times I was very busy I may not take them excaclt same time and sometimes not as much because honestly I didn't need it, but Istay SOSO thirsty like cannot drink anough water to satiate the thirst and more tired n sleepy than I was before so i wondered if maybe i shoud taper a bit. for only two days i dont take one of the 4mg doses and i have been sicker than anyday ever of my life. i have harrible headache, sweatchills nand feeling like fainting,throwing up till theres nothing left to toss , my legs cramp and my feet and hands swell. well they still did much of that PLUS I stayed constipated b4 i forgot a dose. how long will i still feel like i'm withdrawals? I havent been right the entire time. I was told that I would get my energy back and sleep bettr and would stay on for pain mangtmt. But I'm constant sleep like my brains asleep but dont sleep at night and all the other symptoms have been there they are getting more instense. How long will this last? Im losing my @$#!@ mind!!
