Anhedonia Fading?

Hey guys,

I have schizoaffective bipolar type and have had pretty bad anhedonia for 2 1/2 years. A little over a week ago I started lamictal and since then I have been feeling a sort of calm, felt some euphoria listening to music a day ago which I havent felt in a long time, and have noticed I havent some motivation to get out of bed and on with the day in the morning. Are these early signs the lamictal will help fix the anhedonia?
