Yep, I can relate.
When I am high or normal for a while, all memories of the chaos seem like a hazy fairytale and I begin to wonder if I really have bipolar - if it is a real illness.
But I rapid cycle, so it isn't long before I get jerked back to reality and renew my dedication to my exercise, diet and meds. The danger of abandoning meds lies in long cycles where everything seems fine and memories of bad times fizzle out.
