Flu & UTI...leaving on cruise!

Some advice please.  I am 74 & over past 6 years several diagnosis:
MycoPlasmaPneumoniae, horrible with no treatment of asthma symptoms, next treating asthma symptoms, then finally diagnosed with a form of ABPA. Reaction to aspergillus (aspergillosis) under skin & high IGE 2200 but no evidence of blood antibodies. Treated with 15mgs prednisone every OTHER day for 3 yrs w/exacerbation occasionally. Last Dec "11 was able to get off prednisone & best yr ever until now.
Caught flu which became UTI.w/yellow/tan mouthfuls when coughing. Had pred 13 day pack for breathing. Then short steroid shot & 100mg of doxycycline. Helped color of plugs & cough but still white mouthfuls of sputum.  Doxy has made me feel weird, little dizzy & yesterday & today nauseated. Very tired.  Leaving on Saturday for fight to FL & cruise!! What can I do to get better?  Should I ask for another antibiotic & get off Doxy?  Urgent to get well!  Please answer soon.

Hi!
If you are leaving on a cruise then please consult a chest specialist ASAP. They have doctors on board on a cruise but they can attend only to minor ailments and give first aid. You may need intravenous antibiotics, or steam inhalation or oxygen therapy, or bronchodilators. It is difficult to comment on net. Please consult a specialist and please postpone your trip if the doctor advises so. Take care!
