To Lisa Carper: You asked- "Question: why will you choose 2.5 mgs or 10 mgs? Could you try, say, 5 mgs? Or any amount in between the 2.5 and 10." I only saw positive changes when I started taking 2.5 mg of NADH a day and then again when I increased to 10 mg a day. When I took 5 mg and 7.5 mg I was no better then when I was taking 2.5 mg. Thank you for telling me that taking ginger helps Jeff's dry mouth. I will try taking some and see if it works for me. Diane -- Diane Turner [log in to unmask]
