i remeber early on recovery from pain med addiction i read vitamin B12 can help with depression for ladies. so i tried it out figuring we all had the same hormones just different amounts. i used the tablets that dissolve under the tounge. I honestly feel i had a deficiancy. that first month was alot of chocolate and b12. i wont promote altering the way you feel much but it is a vitamin and unlike other vitamins there are no ill side effects like having too much calcium or iron.
