I often feel an episode coming on - up to 15-30 minutes ahead of time. It gives me a chance to tell the people I'm with "Hey, I'm starting to climb". When I'm alone, I let it roll and STAY SAFE!! I just had a medication adjustment, so I know I'm more prone to cycling right now. Keeping up with my T and psych doc is important. Long and short of it - you're not unusual! Hope you feel better and good luck.
