I experienced the same thing with the first supplier I used. I purchased the oil based on the price….i no longer do that. I research the company and talk to them about their process and base my decision on the purity of the product. There are now so many ways to take CBD’s that if one doesn’t seem to fit or has negative side effects, try another delivery option. Also, I would try changing the supplier and purchase only the best product that you can find or afford. I had a negative experience with one supplier where their product gave me a bad headache, I changed suppliers (little more expensive) and the headaches stopped.
