Hello. I Have Been Taking Clonazapam .5 Every Night For

Hello. I have been taking clonazapam .5 every night for several years for anxiety. Me and my doctor have discussed me quitting. He said to taper off. For the last 3 nights I have taken only half of the .5. I am already experiencing insomnia . Should I continue to keep taking only half for the next 2 weeks then half every other night for 2 weeks to slowly get off of these?? I just read that it is possible that it may cause me to have seizures??? I've never had one before so I'm a little scared of the withdrawel symptoms. What are the chances of something as drastic as that happening??
