I'm pretty much ITA w/ the other ladies. My 1st transition was about 14 months until I cut the last relaxed ends off and my natural hair was shoulder length.
One of the ladies mentioned heat damage from flat ironing, and I think I may have had that too last time, so this time my 2nd transition is 100% heat-less. I air dry naturally or plop w/ an old T-shirt then twist or cornrow. I will not trim my ends for 6 months. I began my 2nd transition in November 2007 and things are going well.
Also, sulfate free poos, or CO wash only are also good for transitioning. Ditto the other ladies, LOTS of moisture.
Good luck and ENJOY your transition - this is the time to experiment with all kinds of styles, products and tools.
