Zithromax Z-pak Aspertane, Smoke Alarms, Senses, Discern, Sweet Sour

Last spring I was given Zpak for flu/cold syptoms. I finished the first package and still experienced the same syptoms and discomfort with breathing. The doctor had given me a prescription for 2 paks and instructed me to have it filled. Because from her experience sometimes a second pak would be needed. The side effects that I have and still having is the lost of taste and smell. I can only differentiate whether something is sweet,sour, spicy or tart but I cannot give discern if its smell. I cannot smell fragrances, or smoke. I can taste the aspertane in sodas, but cannot tell the flavors of soda. I can smell the chemical that binds the soaps, lotion or perfumes. I also have had the experience of going to an ENT and guess what he also prescribed the Zpak for the congestion and fluid that I have been experiencing in my ears. I am very frighten regarding the loss of my senses of taste but the most frightening thing is the lost of smell. I cannot leave a pot on to boil without watching it now. A pan boiled dry and thank godness for smoke alarms. I so perplex with all of this. I've been dealing with this for almost a year now and still no sign of being able to smell or taste in site. I'm not a smoker and have had no other reasons for this to linger.
So what can I expect? Will my senses of taste and smell ever return? This is very heart wrenching and frightening. Since I alone most of the time.
