Vi-Q-Tuss and vomiting

After suffering a week with a nasty cold I went to my doctor and was diagnosed with bronchitis. As well as an antibiotic I also got Vi-Q-Tuss for my cough. I took it as ordered at bedtime. At first I was feeling a bit tipsy, but it did stop the cough. I started to feel drowsy so I went to bed and as some have complained....I cannot sleep. I also seem to have a side effect that I haven't seen here yet....I am VERY cold. Freezing to the point of shivering uncontrollably and nothing seems to warm me. I was under many blankets, mind you I live in Florida and it is not yet cold outside despite the time of year, in fact we had the air conditioner on during the day today. But, thankfully, no nausea or vomiting. Even though these side effects are a bit bothersome, I suppose it is a small price to pay to stop that painful cough I was dealing with, so long as the effects don't worsen. I will however ask to try something different next time I need a cough medicine. There has got to be something else I can take that will work at stopping the symptoms without causing such weird adverse effects.

Sick on my stomach ,vomiting,dizzy, feel as if i was going to pass out, could not walk by myself, someone had to be with me untill it was out of my system.
