I have had to restart it to control hunger. I have only taken two smallest doses (25 mg tabs) and I have already had one episode of forgetting a word. As is typical of such memory lapses, the word suddenly came back to me several hours later when I was not looking for it but rather was simply eating dinner.

But I have to control hunger so I am afraid that I will need to live with occasional word retrieval problems. Luckily I know a lot of synonyms, so there are workarounds...
