Has anyone suffered from side effects of this medicineI am hoping that those who had suffered the side effects have recovered. Can anyone comment on their recovery? I took the 5-day course 2 weeks ago and I am still experiencing slight dizziness/unsteadiness when I walk, a strange fuzzy heavy head pressure, sporadic anxious/nervous feeling like I was going into panic attack mode, and also occasional stomach digestion discomfort. I hope none of this is permanent. I know that the drug has a long half life and it's probably still in my system or wreaking havoc. Can someone comment on their experience and whether these side effects will go away?
