I was very depressed/mixed last night with SI. Came on fast after being euphorically manic for 6 days. Was given 10mg of Olanzapine but 4 hours later I was distraught and unable to sleep (It was midnight) so the nurse gave me 20mg more of Olanzapine (Zyprexa). I slept well until about 7 am - six hours sleep. Felt hungover from meds but now, 10am, I am back to euphoric. Not sure what that was all about. Just hope it doesn't return.
