i know how you feel. i have been struggling too. no motivation.
i recently started taking mega buzz..which has bee pollen and other natural ingredients in it. it does help. but like anything else you have to believe in it. i work at a health store (started right after i went off opiates 3-4 months ago). try a health food store near you. they can't and won't perscribe but should be able to help you.
someone else mentioned omegas...dha and eha can help for many things, one of them being energy.
i am not a doctor, therefore, you should discuss anything recommended on here with your doctor or a pharmacist. any herbs especially (don't take if on blood thinners).
natural medicine is good, but you still have to be careful and no what you are doing. check your multivitamin and see how much d3 it has in it. i take 1000 IU a day. it supposedly helps fatigue, as well as a mood elevator and chronic pain.
hope this will help..
let us know if you find anything that helps you!!
