Azithromycin 3 Day Dose Pack Lung Infection, Night Sweats, Home Remedies, Antibiotic, Diarrhea

My doctor prescribed this antibiotic for a lung infection (due to cough which by the way still have), the first day i started on the pill, i had diarrhea, which i know is common while taking this medicine, but now two weeks after i took the last pill, i am having trouble sleeping, night sweats, palpitations (so bad i thought i was having a stroke),still diarrhea,lightheaded,gas. Please, has any one out there had any of this symptoms while taking this antibiotic and if you know how long does it take this medicine to be out of my system. I think next time i have a cough i will go like our ancestors did it make my own home remedies which by the way work better and without any side effects.
