Shortly After Beginning Osphena My Vision Became So Bad That

shortly after beginning osphena my vision became so bad that I could barely see to drive. I was also experiencing double vision ( the two combined scared me half to death. I also had headaches, confusion, etc. I STOPPED taking osphena immediately using my own common sense. I do not believe that near enough studies have been done; especially on human beings. What's your take? Thank you in advance.
