When you are sick it is very hard to deal with a high protein diet. My advice, if you ever get sick again, is just help yourself through your illness first, that is what matters. If you have to eat saltine crackers to settle your stomach or can't eat at all, just get your fluids, and worry about low carbing later, don't knock yourself out. So don't beat yourself up about it, but if you get sick again, as soon as your tummy is back in tune, get right back onto the wagon and eat for your WOL. Just don't worry about low carbing if you have the flu, heck when we have the flu the last thing we can do is eat.

Take care and now you are back on the wagon so don't fret about the past.
Good luck
