> There's one negative side effect I've noticed - I feel less smart than before. I'm not sure if it's a real thing or not, but I feel I can't fully express myself in English. I consider myself quite a fluent speaker, but my vocabulary is still quite limited compared to my native language. It's enough for 99% of the conversation I have, but whenever I say or think something, I have this feeling that I lack words to precisely express what I want. I've got the very same problem. The frustration at the lack of precision of my communication is what kills me. I suspect it's perception only and caused by the fact that my native language has more expressive grammar that allows entire "She would have gone" sentence be expressed as a single word - a conjugated verb - and include 100% of the information of the one in English.
