Sorry,
I'm not ggod enough to have PR all the responses here, but I am not into the meditation or herbal remedies of any kind for memory or reading.

But I once bought a course on photgraphic memory and it really worked. You have to prctice it or it will fail you. Basically you care a place like your house - a room or even the inside of your care. memorize every piece of furniture and use that as a place to mentally place things as you try to memorize them Always be vivid. remeber how things smell look, taste - whatever. Now every time you need to remember a list put that thing on one of your memory hooks. place them in order in your mind. that's it.

It works for me.
