What Should I Do About Brief Seizures Triggered By Lack Of Sleep Or Mental Stress, Which Have Persisted For Years?

Greetings, Back in 2010 was the first time i exprienced having a seizure. At first i wasn t sure about it, but with the passage of time I started to realize that seizures occur to me for 1-2 seconds only whenever there is lack of sleep and putting stress or pressure on mind while calculations or some technical work. I took medications during 2014 when i consulted a doctor. But later that year I left medication till date. With time going by, now im in a position where I know when seizure can happen to me. If i didn t sleep well or whenever putting stress on something it happens. What i feel is relatively throughout years it has been under control to some extent, but still it is enough to not let me do technical work or drive as it can trigger at some stressing point. Kindly guide me on this.
