I had to come off lamotrigine really quickly due to an allergic reaction. I was on it for 4 years at 300mg.

I tapered off in 3 weeks. The major problem I had was dizziness. And my depression returned almost immediately and I've been depressed since then (2017).

Other than the dizziness and return of the depression, I didn't have any other issues.

The dizziness went away about a month after my last dose.

I hope things work out for you.
