depression
"I've been under treatment for depression for over 10 years and I've tried Prozac, Wellbutrin, Zoloft, Luvox, Cymbalta, Efexor and a few more. Efexor was by far the worst! Instead of making me awake I was sleeping around 16 hours at day and little I know my blood pressure was always high. 

I've started Lamotrigine about 2-3 weeks ago and I'm still on 25mg, but I can tell the difference in my energy and I'm not taking naps during the day at all!!! I don't even feel like it. My energy level is great, something that was making me even more depressed!!!! Life is good again!"
