I used to overbuy, but thanks to Lithium, I no longer do. I had a Lithium intoxication when I was at a high dose, so my dose was reduced but it is just as effective - no more urges to overbuy. It is not that I exercise will power, no - I just do not have any urges. I still have a long way to get rid of stuff I used to overbuy, but one day my apartment will be clutter free.
