Had trip/bypass 8 2009, always tired + fatigued even early morn, breath deep but lungs don't seem to process air, more irritable lately, headaches fm time to time. Had checkerboard alergy test twice at onset of itching 1982 & 83. Allergic to cockroah excretia & potato mold both times. 5 mg tabs stops itch but gets unbearable after no dos for 3 or 4 days. Is there any med that might releave side effects and prevent itching? Thanking you in advance.
