Aciphex side effect?

My pcp put me on Aciphex 20 mg for acid reflux. He said he could hear the acid in my esophagus.  Is that possible?
I have had fatigue for almost 2 years...after many tests..no cause found. Since starting the medication 5 nights ago, i have had even more.fatigue, lightheadedness and spaced out/drugged feeling...has anyone else felt this way?  I am calling in the morning to make an appt.with a gastroenterologist with hopes that they will order some tests.

Thanks!
