If you have problems, you should probably add flux (make sure to extract fumes if soldering with flux for a while). Some say there is never enough flux.
Depends on brand. And my head always hurts after inhaling them for more than a minute without a fume extractor. (I just use a PC fan and some old who-knows-what HEPA-like filter discarded from ventilation equipment. For quick jobs, I hold my breath and/or move out of the way.)

They don’t want you to know, but you can extract all the fumes and flavors using only your nose!
Seriously though, flux fumes do have a somewhat nice smell to them.

Remember that all the flux you use will need to be cleaned off eventually. That can sometimes be a pain if there’s a lot.
I know, I mentioned it in that long comment
