I'm glad that every glass of water I drink has infinitely small concentrations of every possible homeopathic remedy, so I know I will never get sick from anything.
"water molecule retention of energetic information"
1) this doesn't happen. Basic chemistry and physics.
2) if it did, every molecule of water on the planet would already have the signature of every substance that has ever been, because the water cycle has been going on for about 6 billion years and it all gets churned up constantly. So, again, if homeopathy worked, just drinking plain untreated tap water would have the exact same effect.
If there were really a "memory of water" which was detectable by any means, then any lab in the world should be able to take an unlabeled sample of homeopathic medicine, and one of plain water, and using whatever techniques are claimed to be able to detect the difference, figure out which was which. This has never happened. The only people who have claimed to be able to tell the difference are those who were already proponents of homeopathy in advance of the experiment, and they do not explain their methods, (or when they do, those methods don't work for anyone else).
