I've been on Lamictal a few years now, it has NOT taken my ability away of feeling elation, it does not numb you.
Different people respond differently to different meds, when you are taking the one right for you, it is great. I can't understand why anyone, including myself, would prefer to stay in a funk, when there are ways of keeping stable, episode free. I guess it's all up to one's preferences and what they finally decide. I prefer stability, regardless if it means taking 2 pills a day, and keeping with pdoc appt. every 6 to 8 weeks.
There is no sin to take medication, it's a sin not to and to spend life being miserable, when one doesn't have to. I learned to accept that last sentence about 6 years ago or more.
Whatever you decide, I wish you luck.
Take care,
DE
