Yes I would quibble about the use of the word "lost" here just because I have a complicated relationship with my bipolar and episodes....but I get your thinking here and like the question. I don't know if I can or even want to tally up the sum total of time spent cycling or in an episode (eeek) I can prob think of some. My last "big" one I "lost" 5-6 months to mania and then crashed and lost five more to depression. My big mixed that got me dxed lost me three months and then I lost nine months to Abilify. That **** did not like me.
