I take clonazepam for my generalized anxiety disorder. I've also taken Xanax, and this is what my psych has told me about weaning off of benzos.
You're taking a VERY low dose at only .5mg a day, and haven't been using it all that long. What my psych suggested, at low dose, is to go down from one tab daily to 1/2 tab daily for two weeks, then 1/2 tab every other day for two weeks, then stop. Do NOT try to quit clonazepam cold turkey, as it can cause seizures.
That said, I'm not a doctor, so if this drug was prescribed to you legally, I would call your doc and ask. This probably doesn't warrant an office visit (though some insist so they can bill for it), but it seems like something that could be answered over the phone.
I don't think you'll have a difficult time with this. Your dose is quite low. Best of luck to you.
