I have been on Lamictal, or the generic rather, Lamotrigine, for 6 months. No real side effects for the first few months except a little more tired than normal. I started at 50mgs and am now up to 100mg. I was diagnosed with hypothyroidism, a slow thyroid, 2 years ago. So I take medicine for that and have been able to maintain a healthy thyroid. Except in the past 2 months. All of a sudden I have gained 11 pounds (with no change in eating or exercise habits, I am very healthy and active!!!) and my thyroid has slowed down and I am become sluggish. 

Suddenly a light bulb clicked on that it could be my Lamictal. I've read of some other people having similar experiences. Can anyone help me with this or share your experience? Do you have another drug similar that you would recommend? So frustrated here!

Thank you!
