I read somewhere the other day that all drugs starting with 'fl'; are either fluoride based or have a significant amount of fluoride in them. I haven't clarified this yet. Can anyone confirm or deny?

Also some theories abound that fluoride may be responsible for the underpinnings of conditions such as CFS/Fibromyalgia. Again I haven't pursued research on this - however I believe empirical evidence must be scarce on the ground - as it is still mandated for usage?
