sick of shakes!!!

I'm 2 weeks post op and in the same boat...I'm allowed purees (was from day 4) but not really interested at this point...I have three different protein shakes to choose from (all Unjury), Chocolate, Strawberry and their Protein soup which is my favorite by far. I HATE the chocolate now and actually dread it. I drink water and one can of low sodium V8 juice (only 30 cals.) and easily get in my protein and liquid requirement, but my tastebuds are pretty miserable right now! I want to add coffee to my chocolate unjury shake, but was worried this would work against the liquid intake since it's acidic and has caffeine, is it negligible?
