I am trying difficult child on b vitamins and omega 3's as they have helped me with my patience, and lord knows that poor kid needs some too. Is there any difference between using flax seed oil or fish oil? Is one more effective? For now we are going with the flax seed oil as the caplets are a little smaller and have a little more omega 3's per capsule. difficult child is sure that these are going to kill him, so we are just getting him used to the idea by having him take one in the morning and one at night, and will get up to 3000mg per day eventually. That is the dose that psychiatrist says research shows is accurate so I figure we will shoot for that.
