I also cold turkeyed... Its was pure hell on earth.
I had cold sweats, body aches, shivers, hallucinations, sky rocketing fevers, I was so exhausted I gave up on getting out of bed, all of which lasted almost 2 weeks... My family said it looked like I was coming off of heroin.
Ugh just ugh!
Never again. Never
I am not at all sorry I did that though, because I needed to, but I wouldn't recommend it.
Sounds to me you're experiencing withdrawals, hopefully it will go away soon.
