Increased my dose feel worse

Hi i was wondering if someone could help me i have bein on propanolol for just over 3 months now and on wednesday i increased my dose from 120 mgs to 160mgs i was feeling ok on 120 but still had symptoms,now iv increased my dose iv got tye 24/7 dizzy feeling back the fuzzy head feeling is there all the time again! I was diagnosed yesterday with a slight ear infection so im now on antibiotics and due to fly to tennerife on tuesday so im really worried as i feel iv had a step back in the wrong direction! Is it normal to feel bad when your dose is increased ? The ear infection probably isnt helping to either :pensive: Any help would be appreciated
