I'm experiencing what I think are side effects from Lamotrigine; I'm on a pretty low dose, 2 weeks on 25mg and last weds started taking 50mg. Yesterday and today, I've got what's best described as a "low pressure" headache. Paracetamol/Neurofen don't really seem to touch it and it's not affecting my sleep, but wondered if anyone else has had a similar experience? Should I wait longer to see if it goes away? It makes me feel pretty tired and don't fancy this on a daily basis!
