I have done what you are doing. In august I felt I was tired of being depressed and my doctor wasn't helping me so I decided to start taking the Prozac (10mg) by itself - no mood stabilizer or antipsychotic. I didn't know what would happen As euphoric hypo/mania was new to me.

Within days I was hypo and soon after manic. But unfortunately for me I only feel happy for about a week. Then rage takes over. It only took an annoying tone from my husband to completely flip the switch from euphoric mania into dysphoric mani, and by then I was trapped out in space. I began seeing things, hearing things, and believing that a being was implanting thoughts in my head. And at that point my pdoc became uncooperative, believing I was saying everything for attention, so he refused to see me.

Long story short I ended up hospitalized after attempting to hurt myself because the thoughts told me to.

There is an ugly side to mania that you may or may not experience, but if I read your post right you've only experienced mania once? You don't know how your brain could twist things around on you. I don't know what meds you're on but I hope you have a fast acting antipsychotic handy to bring you down because mood stabilizers take time and you may not have time.

Good luck! Be safe.
