Hi JG. I have been Opvido since April. I had scans about 3 months after I started that showed tremendous improvement. It is true that the first scans aren't always easy to interpret but I believe that unless there has been frank progression, people usually stay the course for another 3 months or so. I've had no side effects except for my thyroid not working very well. I've been on thyroid medication for a couple of months and am having no symptoms with that.
I do have mild neuropathy in my hands and feet from cisplatin I took almost 6 years ago. It doesn't bother me enough to take anything for it.
I wish you well on the journey.
Sara
