No, you're not a whiner, for certain. When I started abx I claimed to have got through the early days easily, but that was really because I had no memory of them. According to David, I slept most of the first month.
What you seem to be experiencing might not feel pleasant, but is what I and many people went through. You are killing the pathogens which have been helping to make you ill. Basically, if you feel absolutely nothing when you take a course of antibiotics, they aren't doing very much. Lots of people when given abx by their GP feel rather ill, so go back asking for a change of medication because they think they are allergic or somesuch. In actual fact, more often than not, they feel bad because the abx are working.
Allergies start almost immediately on taking something: not a week or so later.
Now, your doc asked you what you were doing to make you look so well, I am telling you that you are writing better than the first post I saw. You've a long way to go, but this is an excellent start. If you go to see your GP tomorrow, tell him I told you this!
