Azithromycin 5 Day Dose Pack and panic attacks

Not sure if it's the Azithromycin yet, but since taking it, I cannot sleep. Almost seems like Im having panic attacks that are preventing me from sleeping. This is outrageous. Day 3 and still no sleep. I think Im going to stop taking it and see what happens

I felt like i was going to die! I paced back and forth like a restless tiger in a cage, nervous, panicky, jittery, and restless. I felt like I was choking on flem and I was ready to go to the hospital! As for sleep ...good luck with that. I finally fell asleep at 3:30 AM and was up by 6:30 AM! This has been going on for two days now. I called my Doctor and he said that he has prescribed this medication to thousands of patients and never has heard of a reaction like this. My doctor told me to stay off of the meds for two days to see how I feel. I'm afraid to take these meds or anything else again.
