Martin, As you know, this is a real problem. I started taking Pycnogenol (available in health food / vitamin stores) and think it has really helped with energy. I take 60 mg in the morning. Dosage is up to 1 mg per pound of body weight. For example: if you weigh 160 lbs they recommend up to 160 mg per day. Therfore, I'm taking about half the recommended dosage and do OK. Good Luck, Gray (50/3)
