My 23 year old son has been diagnosed Bipolar II and has been on 1500mg of Depakote for about a month. He is very sleepy and has a hard time getting up in the morning. He is also on 50 mg of Seroquel and went on this med about the same time so maybe the combination is causing sleepiness? How long might this lethargy last? It seems like he is a little mentally fuzzy too. It seems like his personality is a little dulled by this med. I am wondering if over time, the side effects subside.
