Hi frogy,
I tried to post this a couple of minutes ago but it didn't show up, so I apologise if it comes up twice.
I've had several bad infections. You should be taking or have finished some really strong antibiotics, doxycyline and Flagyl or Keflex and Flagyl?? About 10 days/2 weeks? Feeling "wiped out" is normal after finishing those, but if you still feel sick then you need to go back to the doctor.
As Chris said, once you've finished the ABs it will take a few weeks to feel better. Gynae infections can be very serious. A multivit is a good idea...get plenty of iron in your diet or otherwise.....and just nurture yourself. If you still feel quite pulled down in a month's time, then I'd say you should see your doctor again.
