Should I stop lamotrigine?

Trittico caused my visual snow and when I stopped taking it it stopped. However, I also started taking lamotrigine, but I don't see it doing anything. I'm currently taking trintellix 10mg and I don't think lamotrigine is helping me. Unless lamotrigine has destroyed my trippy feeling that I've had since childhood and I feel uncomfortable without it. Should I stop taking it then?
