Hi, Thank you for posting your query. I have noted your symptoms, medications and diagnosis. Epilepsy is a chronic disease, and it needs medicines for a long period of time, for adequate seizure control. Valparin chrono (sodium valproate) is a good anti-epileptic medicine and is reasonably safe. Regarding smoking, there is no direct interference with epilepsy or the medication, but is generally un-healthy, and is a risk factor for cancer, stroke and heart attacks. Alcohol, if taken occasionally, in small amounts may be alright. I hope my answer helps. Please get back if you have any follow up queries or if you require any additional information.
