Thanks very much @Jake for elaborate answer.

very true, if the side-effects are totally recoverable then definitely, no point switching; but was wondering if switching would limit the amount of harm a drug does on given organ (like my liver , although largely recovered, is now said to be still susceptible/ prone to ....)

quite rightly, and as my docs also say, all epilepsy drugs have some side effects and there are few risks in unnecessary switching.

yes my medicine is not ER, shall talk to doctor on my next visit. have also started regular Yoga.

Whats so different about Lamictal ?

thanks again and Best wishes.
