HI , My Doctor Currently Has Me On Metoprololm And

HI , my doctor currently has me on metoprololm and micardis plus 80/25 as I have consistantl y high blood pressure, I also take endep 10 mg twice daily, initially the endep was to help me sleep but has helped more with fuzzy head fellings than sleep. I also take Imigran for migraine pain, my weight has seemed to increase lately, so I have been looking for answers, what I am reading is that the beta blockers can cause weight gain, and that I may be better off on Wellbrutin, can you tell me if it would do the same thing as the meds he has me on, without the weight gain.
