It's been over two weeks since I tapered off and stopped the Lamictal. My heart rate now is much lower again, and I don't have major palpitations and racing heart when going up stairs. My resting heart rate now hovers around 55-68bpm. Going up stairs at normal pace, it goes only to about 110bpm. This is much lower then when I was on the Lamictal.

My psychiatrist kept telling me that the Lamictal shouldn't have caused that, especially since I had reduced the dose down to 25mg. I'm not sure what else could have caused my higher heart rate over all those days, because it was continuously high until after a week of stopping Lamictal.

Perhaps it was an interaction between Lamictal and one of my other meds. Who knows. But I'm not going to take it again unless I need it.

I'm also thinking if maybe I have some type of Dysautonomia condition. Because occasionally I get chills and have low body temp.
