Barb,
You have done a 180!! Good for you. Now go forward and keep that new outlook in the forefront.
I missed the fact that you were already taking Clinda. So no need to switch. It's more potent than amoxil but, can cause GI upset and is know to be a factor in developing c.dificile infections. So if you develop the trots get to your doctor or you could be in for a ride. Usually this only results from high doses over longer than average periods of treatment but, to know is to be able to react.
All the best!
(dentists are people too. LOL)
Cheers,
Mike
