How to remember things

For a few months, I've had this chronic problem of lack of hunger. After waiting around and procrastinating for around three months, I finally visited our family physician two weeks back. He diagnosed me for "agnimandyam" (which roughly translates to a slow-down in appetite). He gave me a medicine, which I had to take twice a day, once before breakfast and once after dinner. It went without saying, any miss in the schedule, and the medicine would not have the desired effect.

Now, how is it that I take an instruction like that, and make sure I follow it? How does my brain know automatically from the next day, that I have to have the medicine as soon as I get out of bed? Of course I could write it somewhere where I'm sure to see it, or set a reminder on my mobile - but the point is, the brain is actually capable of remembering without these external aids.

I actually managed to follow the course, without any such device, even without anyone having to remind me. I tried a new technique. The basic idea is, it is possible to condition your brain and make it remember what it needs to remember. Here's what I did, I repeated to myself several times before I went to sleep that night, that I have to remember to take the medicine the next morning. While I did this, I imagined myself actually taking the medicine, tasting it, and feeling it go down my throat. The next morning, to my pleasant surprise, I automatically remembered to have the medicine. The repetitions that I did, and the mental image that i had carefully built the previous day had helped my brain form new neural pathways to remind me of the new thing that I had to remember from the next day. It was a lot easier the next day, I didn’t have to remind myself as hard as I did the first day and gradually, this conscious effort gave way to unconscious habit, and soon I started to remember to take the medicine almost like I remember to brush my teeth.

Well, finally last night, I finished the course of medicine, my appetite is now back, I am eating and sleeping as good as ever. And most importantly, I have finally cracked the mystery of memory - after countless lost umbrellas and locked cars.

Funny thing though, I just remembered, I forgot to have dinner yesterday..
