Hey that's fantastic!
My energy levels were also very good at lower dosages. I stayed at 62.5 mg daily for quite a long time before changing course and increasing. What is your current dosage?
Sorry I don't know what to make of the rash.. perhaps it's related to DSF, perhaps not. You may want to trial some other brands of deodorant.
