I saw the psychiatrist today and my meds have been increased, previously Seroquel 100mg with 300mg Lithium ER. Now I am on Seroquel 200mg and 600mg Lithium ER (once in the morning/once at night). I also have to get lab work done once a week for the next 4 weeks (no real point in mentioning just wanted to make note of it

).
I've never taken Lithium ER in the morning, does this make you sleepy or foggy minded? I plan on starting it tomorrow so I have the weekend to sort of feel out whether it will be good in the morning for me or not. My doctor said if it doesn't work out then it's fine to dose all at night but he'd prefer I try a morning dose first.
I am still on the fence with the recent DX of BP2, I have always known it to be ADHD with Major depression (my DX for 10+ years). I'm not against it, the Lithium/Seroquel combo are doing better for me than the SSRI's ever did, but it's new territory for me. No real point in mentioning this either, just feel like writing it down.
TLDR; Does Lithium make you sleepy in the morning?
