I find that too...the whole afternoon/evening downswing. I wonder if it's related to the meds or to our natural rhythms...like our body wants a nap.

My downswing typically happens from 2-4pm. Sometimes I lift out of it after that, but sometimes it lasts until I can go to bed...and damn do I ever want to on bad days like that. I'm still on today's downswing at 6pm. I figure I'm just tired from working and invasive thoughts.

Hope you find what helps you. And I agree, take the meds when they feel best to you. Everyone's different. Lamictal doesn't make me drowsy at all. If anything, it's making me rapid cycle and be hyper at night. Not that I'm allowed to change the time I take it until I can see the new p-doc. Sigh. We'll make it through this process!
