Bests & Worsts Reviews from Amazon

I was very excited to try Can-C and used it for five weeks. I did notice an improvement in my eys. I have dry eyes and it helped in that respect. After about three weeks I started getting constant head aches in my forehead region and also was very tired. I never nap but found myself napping every afternoon in order to stay awake. One day I forgot to take my drops and the next day noticed I didn't have any headache. I thought maybe the headaches where due to the eyedrops so stopped taking them. The next couple of days I noticed I wasn't tired anymore and did not need a nap to get through the day. I am so disappointed that I cannot take these drops. They really did help, but it's obvious I am allergic to them. I am a 78 year old female in very good health. My only medicine I take is Synthroid. I do take vitamins. My cataracts are minimul at this point so I was hoping to eliminate the need for cataract surgery in the near future.
