How much time should I take off?

[i like wimmins]

I stopped using ecstasy for a couple years, and then started again about a year ago and it was like me first time all over again. I got over zealous though, and there have been a couple months where I have done it every single weekend, and weekends where I've done it all three days. My tolerance has skyrocketed in the past 8 months, and I am up to approximately 6-15 pills per night now when I do flip. I follow the tried and true method of doubling up if I take the drug multiple days in a row...but when you are eating 5 pills to begin with, the numbers get pretty high. This is, of course, ridiculous, dangerous, and expensive.
I have stopped hitting a peak, and for all the pills I eat I am barely able to scrape out a high that lasts as little as 2 hours.
So, I have decided to stop doing ecstasy...again...but I was wondering how much time I should give my poor little brain to rest up before I start using again?

Also, I saw something on a talk show about frequent E usage making your brain look like a honeycomb...is there any truth to that?

Thanx
