I am so sorry you're going through this. Here are some supplements & herbs that should help you. I'm not sure if you would need a higher dose than recommended on the packaging. Start with that before you try to increase. CARROT EXTRACT. FISH OIL. AMERICAN GINSENG. ZINC. MAGNESIUM. There are others, but I can't remember them all. Start with these, then see if you can find a homeopathic practitioner. Health food stores are a good place to start. Most can recommend someone. Maybe even the manager of a health food store can extend the list I just gave you. Many are quite knowledgeable. I hope this helps you.

~~~~~~~~~~~~~PEACE!~~~~~~~~~~~~~

P.S.
Whither you talk with a homeopathic prac or healt food store mgr, just let them know you're looking for supplements/herbs to reduce your tolerance to medical marijuana. Might be in your best interest to ask these questions only in a state that has mmj laws. If that's not the case in your state, you may have to resort to phone contact.
