I've been off mood stabilizers (due to bad side effects) for over 6 years without a relapse. I just take Clonazam 1.5 mg daily.
I've learned to manage the mood swings. At first, they were much more severe and interfered with my daily activities. They got better as I learned strategies to deal with them. I control my irritability so things don't escalate. I avoid confrontations with people as much as possible. I keep a journal of my moods, sleep patterns, and how my day went. This gives me a sense of control over my life.
I have a very healthy respect for the disease and how powerful it can be. I'm very careful to think before I do anything risky, and try to make the right decisions in my life. Life is a constant challenge, but so far I've managed to survive.
