Most of us on here believe in Omega 3 not just for the withdrawal but for other reasons as well. I had suffered from irritable bowel for about 20 years when I went through my withdrawal. During that time I had tried omega 3 several times, both prescription and OTC. It always made me sick at my stomach. Well since I made a change in my diet about 1 1/2 years ago...no more irritable bowel. So, I did some research on various brands and side by side comparisons. I finally decided on Life Extensions Mega EPA/DHA. it is "molecularly distilled", what is commonly referred to a molecular sieve. I have been on it nearly 2 weeks so far and no stomach problems yet (knock on wood). My wife and I took some samples to her lab and ran a heavy metal analysis using ICP-OES which measures down to 10 parts per billion (ppb) which is the same as 0.01 parts per million and detected no heavy metals at all. She does not have the equipment to analyze for pesticides so I don't know about that.
It is 2 capsules a day which contains 720 mg EPA and 480 mg DHA.
Ill chectk it out and see if I can find it locally. I am interested in finding out the changes you made for your IBS. I know for me it is definitely milk products
