depression
"I've been taking WB for almost two months for chemical depression.  I started with a feeling of being down, lethargic, disinterested for a long period and in the end, a feeling of being defeated.  I contacted the doctor as I'm generally an upbeat person, but I just couldn't shake this.  I have started losing weight (10 lbs so far, couldn't lose before), am very active, belly laughs and feeling of great joy again.  Only side effect seems to be making my minor PE slightly less controllable."
