I am a recent widow, age 58, who has been very tired; am taking thyroid (Armour, ~60 mg / day) and a multivitamin, eating wisely and maybe 10 # overweight; I swim & do yoga to relax & socialize, am active in my church and have a good prayer life. Despite these (& ~ 3 months of counselling a decade ago), I've had a long battle against depression, and am taking Cymbalta (under doc's supervision, of course!) A friend has suggested that I might look into supplements of magnesium and/or DHEA. Might these be indicated? Thanks!
