yeah - not cheap esp out of pocket! but the doc i had in beverly hills was the one who served up the heavy Antibiotics that GOT me here and the guy i had out in the valley wasn't serious enough about listening to me or thorough enough in his investigation. i told him i had mold and his response was "generally in southern CA we don't have mold unless it's the GOOD kind like penicillin..." - i'm allergic was my response... i'm going to give this new guy a shot and see what happens
