This is funny. The only pescatarian I know is a good friend of mine and everybody (including me) make jokes on his account because he is rigid most of the times but makes some exceptions when he feels like it.

My diet is pretty similar, probably stricter during the week, but I am willing to abandon it during the week end, for social reasons.

I don't eat before sessions, but again I eat very little before evening during normal days. I drink strong coffees before and smoothies if I have to kill time, which is not unusual because I am usually early.
