Lamictal caused hypomania for me but it works well for a lot of people. A lot of doctors recommend it because it has fewer side effects and is more helpful in the depressive mood states unlike other mood stabilizers that are primarily anti manic. The flip side of that is true too - Lamictal is not approved for acute mania so many have to take another mood stabilizer alongside Lamictal to truly stabilize moods. I could never be on Lamictal solo because it was too activating.
