Two times this bit of news was broadcasted and both times I listened carefully. The second time they omitted one of the side effects-hallucinations.Why? Is there something we are not being told?(wouldn't be the first time) On the other hand, this should never,iI repeat,NEVER be used as a preventive method. The best preventive method is to be responsible for yourself.I really don't put much faith in any of these so called wonderful pills.
