Okay, when I started Lamictal I had to titrate and but once I got to around 75 mg I think I started getting a boost of energy and happiness. That lasted maybe 10 to 12 days. It was upped again and I got a mood boost. Again for 10 to 12 days. This type of thing happened til I got to 200 mg. I went to 300 mg next and it did not give me any bump in energy or mood. I am now going back down to 200mg or so. My question is, what causes this initial boost of energy, focus, and happiness? What is the science behind what is going on here? What neurotransmitters or channels in the brain does it work on that would cause this energy at first but then calming down later?
