For the past 12/13 year's I am daily taking 1 zipsydon 40 mg tablet at bed time. I am advised to take it for my lifetime. This medicine was prescribed after being affected by deliberate food poisoning and prolonged neurological disorder and treatments. Now for the past 10/11 years I am absolutely fine. Now if I don't take this tablet my nerves will be jumpy and restless during my bedtime and I can't sleep the whole night. Please kindly check and advice how to stop using this medicine and to be normal again.
