sinusitis
"Very powerful med. Doc prescribed for my sinus infection.  Major dizziness within half hour of taking the meds. It stays for about 5 hours. Congestion does clear up really fast. However I took it at night for the first dose and could not sleep the whole night. The 2nd day till today (5th), I took them after lunch and rested. The dizziness is overpowering. I literally can't function but I can sleep at night 2nd day onwards tho it takes slightly longer than usual to doze off. Happy today is my last day and I will probably never want to take this again if I can help it."
