I took klonopin, 1mg, for 10 weeks for insomnia after having mono. I tapered the last 2 weeks. I have what I guess is withdrawl. I get the shakes and tremors a lot, I don t sleep well , get really tired and my leg muscles twitch, and ache- mainly upper thighs. I feel a little feverish at times. My face gets really hot a lot. I have hot and cold flashes. I did have hepatitis and took prednisone for 2 months before starting klonopin. I didn t know you could have withdrawl symptoms after only 10 weeks.
