It's supposed to be for insomnia, but the bottle says to take it 3 times a day at 25mg per pill. If it is for sleep, why would I take it 3 times a day. Anyway, going to follow my old regime for tonight and ask my doctor tomorrow. What I'm afraid of is I looked up the drug on this website and noted that it is mostly used as an antihistamene. I am Bipolar Level 2 and take Celexa 40mg once every morning. My problem is that antihistamines have a tendancy to throw me into major Manic states due to the bipolar. Should I even be taking this drug at all given the likelihood of a manic attack?
