I am grateful for your advice, will continue to read this forum, and learn about the best supplements to use, and how and when to use them. Who knew there was a sublingual B-12? I am just angry with myself for ingesting a drug which has the capacity to poison, without educating myself beforehand. The physician who prescribed cipro mentioned nothing about possible side effects, and of course, I didn't take the time to read the fine print, because I just wanted to feel better, making the assumption that medications are safe. What a rotten lesson. But, on a brighter side, the information I have gained from you and this site is invaluable as I try to locate a physician I can trust, will listen, and educate . . . . Julie
