i usually take Monday off, play a small sessions on Tuesday of Zoom or mtt sng's, then play tournaments Wednesday- Sunday, whilst usually taking at least one of those days off to go out drinking at night (usually Saturday.) sometimes it pains me taking Saturdays off mtt's as the tournaments are pretty big then (2nd biggest of the week.) but if i just play every day i will have no social life, so there has to be some balance and it can't just be all poker.
on Sunday i never ever ever ever take the day off, i have probably missed 1 Sunday out of the last 6 months. for a mtt players who plays for a living it would be suicide to miss any Sunday imo. i will go out on a Saturday but i usually start at 4pm on Sunday so i am usually okay by then. and even when i was really hungover one week i managed to go deep in my 1st time playing Sunday Million. my advice if you go out on a Saturday would be: try to stick to one drink, i usually stick to pints. try to eat when you come in. drink water. it is okay drinking a small bit but you don't really want to be hungover for the Sunday unless it's a hugely special occassion. and even if you're not feeling great you should man up and just play less tables. you can always take Monday off but Sunday are huge.
imo i think you should maybe choose either cash games or tourny's. then play one or the other 90% of the time and the other occassionally. say you choose cash games, you should play these most of the week, then play tourny's on Sunday when they are the biggest. however i would still try to play some cash games on Sunday alongside as i assume they are pretty soft on Sundays. Cash games and tourny's are totally different and you should try to specialise in one before trying to improve the other.
