In their own words.
“I am happy to report that because of cannabinoids I have been able to reduce my gabapentin intake to 300 mg a day and Xanax to 0.25 mg daily and I sleep soundly. I am grateful to have a doctor like Uma, who sees the whole human and not just the pathology, and who has encouraged me so much in my recovery.”
