I am on my 6th day of prozac. I take it in the morning, however, as of yesterday, I felt like my equalibriam was off and didn't want to drive and not really wanting to do anything. I also already have insomnia and take 1/2 of a 10mg of ambien to get me through the night, but last night my insomnia intensified and I woke up 3 hrs later and took the other half. I was told that it takes two weeks to get the full benefits of prozac. I'm a 58 yr old grandmother and never had depression but due to the last year of many sad experiences, my dr. felt my symptoms were depression. I was going to try to take the prozac at night to see if there's a difference. I read on this board how it helps many to sleep which would be a great benefit. So take it pm or am? Any additional input would be greatly appreciated.
