Well, let me just say, I have no idea what to tell you on dosage etc. as I go by the directions on the bottle of DIM.
At present I am not using the other stuff.
I know too, that certain compounds and or drugs work against E differently, (some stop new production while others intervene with what you already have) so you most likely need to be educated or have someone who knows what they are doing, before shooting in the dark. As E is not a bad thing, it just needs to be in a given range, so without knowing what your range is, I don't know much more to tell you buddy.
My questions would be...,
What or why are you concerned about it?
Have you had your blood tested by a doc to see where your E levels are in comparison to your other hormones?
Paul, I agree with your questions.
If someone has high E2 in general something else is going on, potentially the HPTA cycle is not functioning well
Here is a read on the topic.

If E2 control long-term is necessary, then I personally would pursue an AI like anastrozole, not a SERM, and get it covered by insurance. Think about this, you do not read many threads where guys are relying on Erase or DIM to control estrogen/E2. There are quite a few but they pale in comparison to Aromasin, letro and anastrozole.
The effect of high E2 is quick and can have long-term consequences. This is not debatable and I have experienced the fatigue, lack of sex drive, etc. with a high E2.
I have read absolutely nothing that indicates long-term management of E2 is an issue, quite the opposite. However, E2 that is too low WILL CAUSE long-term problems, osteoporosis being a big one.
For what it is worth.
