What dose of Lamictal were you at when you noticed a significant difference in your mood?

I’m on Lamictal 150mg (I think… I’m not going to get my bottle and check lmao) and although I’m noting a semi-decent difference, it’s not significant. My mood is still all over the place and it’s making my life extremely difficult. I just want to know what dosage(s) you guys noted a difference at to give me some hope for this medication
