....yes Sears and many hundreds of medications worse than bonzos and worse than anti-depressants: even my eye drops , long term use especially its frightening what "could"happen. The fact some of us have been on Clonazepam for over 15 years and are still here to talk about it says something! Now I discover my neuropathy and internal tremors MAY have been caused by dental freezing! Nothing is 100 per cent without chance of someone somewhere getting serious side effects - even from peanut butter!
