"I have conversio disorder caused by stress and anxiety that results in tremors. What strain would be best?"
I'm terribly sorry to hear about your conversion disorder. The type of cannabis & cannabinoids is dependent on multiple factors and questions. For example, what is your previous experience with different cannabis products? Have any of them increased anxiety/ paranoia? If the conversion disorder is making sleep difficult, I might recommend you try cannabis products (flowers, vape-pens, tinctures, edibles) with a higher dosage of THC & CBN. However, if these products had side effects in the past, I would either keep the dosage low or opt for products that have a more balanced cannabinoid profile (i.e. CBD & THC). In addition, if you haven't already started working with a psychotherapist using cognitive behavioral therapy or a related treatment, I would definitely recommend you start. Please feel free to continue this dialogue; I hope these tips help!
