I take between 12-15 Benadryl as well as 12-15 chlortabs

Patient: I take between 12-15 Benadryl as well as 12-15 chlortabs and 4-5 500mg Zantac a day to help reduce the sinus drainage in the back of my throat and eliminate the acid reflux it causes me. All 3 allergy specialist I have been to tell me to rinse my sinuses with saline because I had something stuck in there they believed. Tried that for months each time and it hasn’t worked they all felt I should continue with the rinse instead of an allergy test. I’ve had this problem for 8 years. I’ve doubled and sometimes triple dosed with 24 hr Claritin, Zyrtec and Allegra all worked for short periods of time but I’ve grown immune to everything. I’m concerned with the damage I could be causing to my organs. Since none of the specialist send me for a test and I can’t have one done without their referral are there any suggestions from you as to what I can do to get this under control so I can get off all these pills?
