LA, I think you picked up some bad info, or maybe I just misunderstood what you meant.
"It destroys aromatise"
Actually, it simply binds with the aromatase enzyme and inactivates the enzyme. No active enzyme to make the conversion, no estrogen to circulate.
Someone mentioned something about its effects being "irreversible". This is a little funny. However I can understand the misconception. In various studies, aromasin is frequently described as "the irreversible aromatase inhibitor exemestane".
This does not mean its effects are irreversible. It simply means that it irreversibly binds to the aromatase enzyme. The body continually produces more. This is why it is taken every day.
As far as how to take it, people above have generally been correct. It is best absorbed after a meal. The dosage is recommended to be 25mg's/day. Studies have been done at .5mg/day up to 800mg/day. It is at 25mg/day that maximal suppression of the aromatase enzyme occurs, and it does so after 3 days usage. The amount of suppression has been shown to be about 98%.
I'm not sure where the EOD or E3D idea came from. It's understandable with something like anastrozole, 2 day half-life or letrozole, 2-4 day half-life but aromasin has only a 24-27 hour half-life and no study has ever been done with anything less than a once a day dose. Considering that it takes 25mg's for 3 consecutive days for full suppression to occur, I would be very reluctant to advise anything less than a daily dosage. For someone on a light cycle it may be possible to experiment with a reduced dosage but still take it every day.
The only negative associated with aromasin usage pertinent to us BB's is the rise in triglycerides.

P.S. The following statement is very debatable: "I know letrozole is far better than arimidex"
