Anyone had H Pylori bacteria before?

Yesterday I was diagnosed with H Pylori in my stomach. Doctor prescribed me combined antibiotics for 12 days and warned me on the side effects. After reading other people's experiences I'm really scared of starting the treatment. Anyone done the treatment and actually felt better during and after the treatment?
Also what are the chances of my Husband having it too as it can be passed through saliva?
