"I suffer from Chronic Fatigue Syndrome and have been taking this medicine for about 7 years now.  It gave me my life back.  I used to be so tired  that I couldn't get out of bed or participate in life.  The only problem is I have grown tolerant to it, and am at the maximum dosage, so I don't get as much energy from it as I used to.  But I couldn't function or live without it."
