I have had ketamine infusions for my RSD.

I have a cold and a cough right now, and usually a day or two of Advil/Tylonel Cold and Sinus will kick it fast, but this is the first time getting sick after ketamine... Has anybody noticed that after having ketamine that medications arent as effective being that we had 4000 mg of ketamine over 3 days???

I feel like the medicine is not working... Any remedies??
