Here are a few of my own favorites;
Apple Cider Juice(not the vinegar type).
Red and Delicious Apples
I've also had good success with mixing sprite in with various juices(apple cider type) to make it fizzy, and help spice things up. Overall, I'd say the trick here was to do rotations and avoid getting sick of the same stuff(as you yourself mentioned).
Also, on the topic of water(lots to drink), I've found a very helpful method was to work-up an appetite. And so in my case, I'd take the dog out for a walk(for example) and when I got in, I found that I was actually looking forward to drinking water, rather than not. Which really helped.
I've been taking Miracle-Mineral-Supplement to treat a bone infection(nasty business). Which is a condition that I've been struggling with for the past several years now. And though I will eventually go under the knife for it, I've been treating it with Miracle-Mineral-Supplement in the meantime. To which I'd add, Miracle-Mineral-Supplement does what no other Antibiotic could do(even the intravenous types). And so I have no doubts on the effectiveness of MMS against microbial and related type infections.
And while I won't go as far as saying MMS is a cure all to all problems. I'd have no problems whatsoever standing for the fact that it thwarts Staphylococcus infections with ease.
