I got it wrong with your situation Bubby. Please excuse my reaction and words. I just can't bear injustice and I assumed that you were not being believed.
It's going to be OK. You may think you are not moving forward but already you have moved forward a huge step by your wife agreeing to be tested.
If you can get a short prescription for Augmentin DS or even just Bactrim to get you through until the Doxy arrives that will help you a great deal.
Also, get some Benadryl and start taking it daily every four or five hours. 7mls. That will help your body chew up and move out the parasites you have killed already.
You HAVE killed some of the bastards already. Probably hundreds or thousands. FK'ers. Die you rotten things. Rot and get the hell out.
Drink some water Bubby. Make your blood run nice and full to pick up these bastards and their germs and move em all out. Ready for the next go.
