I take high doses of Depakote and Seroquel at night. I also take imipramine, which I think is sedating but which doesn't phase me. To counteract the sedation in the morning I take Provigil.
I used to get my meds through mail order, so all the bottles are identical. And Seroquel and Provigil are the same size and shape, just slightly different colors (Provigil is white, Seroquel the palest yellow).
So last night I made a "tiny" error. I've been awake since my nap Sunday afternoon.
This is one for the record books.
