headaches from acidophilus

I purchased some DDS-100 Acidphilus with FOS a few weeks ago to take with some CandiGone I was taking. A few days later I began to have what I can only describe as infrequent shooting headaches. They are brief, lasting only a few seconds, and occur all day long.

I finally began to suspect that it might be the acidophilus causing this when I took 2 this morning and the headaches began almost immediately. I was taking some probiotics from NEEDS that didn't cause this problem so I'm thinking I better get some more.

Has anyone else had such experiences?

TIA ...
