I have been going on the "alternative medicine" board and have read alot about fish oil, and flax seed. It was very enlightening.
I bought my son fish oil from the health food store and he has taken it along with Ginkgo. He seems more attentive, and alert. I had recently taken him off his meds. though as we had way TOO MANY problems!!
Check out that board...it helped alot.
Goodluck
