At the end of the day Esme and I went out. We wanted to visit the two second hand bookstores we know about in Xalapa, which are conveniently opposite each other in the same street. I couldn't find any book I wanted to buy, nor could Esme, so we went to a nearby shop that sells magazines.
The shop had the latest edition of the Scientific American Mind magazine, which I bought. Then we went to a small place close to our house for a meal. When waiting for our order I browsed through the magazine and noticed an article that expressed my personal experience with a class of antidepressants - Selective serotonin reuptake inhibitors (SSRIs): "... Yet Antidepressants Offer No Cure" and was thrown off my chemical balance.
