Vi-Q-Tuss and noticable

Both my wife and I were prescribed Vi-Q-Tuss. It stopped the cough when we both took it the first morning. I had no noticable side effects, my wife said she was nauseas and dizzy. We both took it before going to bed, and both of us woke with nausea, dizziness, headache, and sweating that lasted most of the morning. We're not going to take this anymore, I would rather choke with the cough. Instead I took, and recomend, Fishermans Friend cough drops to help with the cough..... if you can stand the taste.
