Clonazepam is classified as an addictive drug and controlled substance. Seroquel isn't. I"m not sure why your doctor wants you to take seroquel -- you don't say why here. This is a drug intended for a limited purpose that was marketed illegally for all kinds of things, mostly for sleep because an unwanted side effect of it is a lot of sedation. You'd probably find quantitatively more problems quitting clonazepam, as it's one of the hardest of brain drugs to stop taking. I'm taking a guess that your doc wants you to take Seroquel because of the insomnia from quitting the clonazepam, and I'm wondering if you're doing this with a psychiatrist who specializes in this or a general doc who doesn't. I ask because it seems if you're having withdrawal problems the thing to do would be to slow down the taper off -- the schedule should suit you, not some general schedule doctors use to make their lives easier. People differ on how difficult it is to stop a drug -- some have no problems, some moderate problems, some intractable problems. You seem to be having some mild problems so far. Seroquel is a powerful drug and was never intended to be used for sleep, but docs do get to do this once a drug is approved -- they can then use it for anything they want. Personally, if my goal was to stop taking meds, I wouldn't go on a powerful med such as Seroquel because that just prolongs the problem -- I'd try and slow down my taper off the clonazepam until I successfully stopped it or found out I couldn't successfully stop it, which raises other issues.
