Zithromax Z-Pak and sinus

I was prescribed the 5-day Z-pack for bronchitis and after two days I quit taking it. I am not psychologically and emotionally perfect (who is) but this drug is causing extreme agitation, nervousness, hard intense dreams that leave me fatigued even after a full night's sleep, and depression with crying spells. I am aware that this drug stays in your bloodstream for a long time. It's half-life is 68 hours and after taking 500 mg. on Feb. 6 and then 250 mg. on Feb 7, I still have somewhat less than 200 mg. in my blood today, Feb. 13. Even at today's level I still have no relief from my symptoms and I am praying that this will all go away when the level of the drug gets to a certain point.
My bronchitis is gone and I am trying to live my life as if I have no symptoms (I teach 7th grade U.S. History) but I cannot ignore the fact that I feel like I am cracking up.
I am not trying to bash this drug. Most people are fine with it. Good for them. But some people have these types of problems because I have seen stories like mine on many internet places.
Hang in there anyone who is suffering like me. I hope it goes away and I can return to my life where I get nervous now and again and maybe once in a while I do not sleep well.
This is horrible.
Anyone who has gone through this and returned to normal please respond. I need to hear some good news.

The first day I developed a minor rash on my back that got progressively worse and has spread over a large portion of my body. ENT Doctor beleives I have developed "drug induced lupus" in response to the drug! This drug did not work to clear up my sinus and ear problems. I would suggest another med. The rash and insane itching all over was not worth it!!!!

I took Azithromycin 500MG for 3 days recently for what seemed like mild flu symptoms (sinus issues, throat issues, spitting up some mucus). After 3 days I developed a full fledge chest infection that has hung around for a few days along with a worse cough than I had prior to going to the doc. I am now spitting up more mucus and running nose. I do seem to be feeling better overall (acutually jogged 4 miles today) but after reading the posts I have to think it has caused me some delay in fully recovering....
