If you can't manage your supply because of your condition (pain or similar) then you really need to speak to your doctor to increase the amount you can get or the strength of the product. If on the other hand you just ended up with a massive tolerance, then you need to take some days off to get rid of it. I don't know your issues, so can't really suggest anything more.
I do suggest you explore making some brownies down the line or melt a jar of coconut fat into a saucepan and make some oil, then put the oil back in the jar (it should harden off again once cold and it will keep for a while). Honestly though I would ask your clinic if you can have some oil and then stick it in the freezer or fridge until you have need of it. Plan for shortages and outages, so when they happen you don't run out.
