Oh my, can I relate... I have a similar situation where I have a boring, repetitive job and have to sit at a desk all day long. It’s mind numbing, isn’t it? I have a supply of green tea or Vanilla Coke at my desk for those times where I might doze off. Good for staying awake, not so good for the waistline. Maybe try the smuggle a book thing; put it between a binder or folder to be less conspicuous? Doodle on paper if you’re so inclined, write something (I keep Word minimized on my screen for that). I think in a case like this, mental attitude is key. I treat it almost like a game or challenge in a way. I know that probably doesn’t help much, but I do understand what you’re dealing with. Take it one day at a time for now and good luck...
