I started clonazepam about 2 months ago for anxiety My father was diagnose with terminal cancer. Started 1 mg twice a day. Month later noticed it wearing off about half way through the day. So dr upped it to 1.5 in morn and 1 mg at nite. That worked even better. Was able to function and no attacks. Well Monday dad passed. And now. It seem like its not working at all. Can't sleep or eat. Called dr. It's Wednesday so he's not in. Got appointment tomorrow afternoon. Does anyone have any opinions about taking another half mg to see if that helps. Any thoughts r appreciated. Ty
