Zithromax Z-Pak and virus

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.

I had a raging head cold, something that resembled a brocheal infection and a low-grade fever.

I'm on day 4 right now and really don't feel much better. My head has hurt the whole time and my fever has not gone away. This is probably just a flu, which Zpak does not fix, but I got the script because it was quicker and easier than telling me to chill out for the next 10 days.

I wish I could blame my woes on Zpak. I can't. I think it's the nature of the virus that is using my bloodstream to swim laps in right now. Hopefully time will be my ally. If not, this is living hell.

I've taken Zpak several times (4+) and each time, it worked like a charm to cure ear, nose & throat infections. I think it worked better for me overall because of the short-dosage cycle which made it easier for me to take the full course prescribed (2 first day, 1 every day thereafter for 4 days). Side effects: diarrhea, cramping, headache, feeling "high" or medicine head--taken with or without food. Hard to say if these effects are attributed to meds or to the infection itself. Boyfriend taking Z-pak right now--he reports severe body ache, skin sensitivity (to touch), and feeling like crap. Again--hard to say if from med or virus/bacteria.
