What reasonable diet substitutes for coffee cream are there? I need cream in my coffee. I can only stomach black, when it's excellent, properly brewed and so on. But at work I have no conditions for making excellent coffee - I make do with decent brand instant (lyophilized), I still need cream for it, and I need coffee to work.

And recently I went on a diet. I switched from sugar to stevia, and it's acceptable. But I still use cream for the coffee.

Obviously, the cream awfully cuts into my diet efficiency, so I'd like to switch it to some diet-compliant alternatives that will still make the coffee palatable, not a watered down slop, remain low-calorie and hopefully not cost an arm and a leg (even in spite of how rapidly would that reduce my weight) or require overseas shipping (to Poland).

What are my options?
I can relate to this. I often home roast, and always do pourovers, so I am used to great coffee. Pretty much the only time I put creamer/etc into coffee is bad coffee.

I've had good success with adding hot chocolate mix into bad coffee. You can get fake sugar versions of this, which are zero calorie (and come in convenient little packets), and they will make bad coffee considerably better.

Not sure about Poland, but I suspect you can find something similar there.
