DXM Coughgels

A friend and I have bought 4 bottles of the 8 hour relief robitussian cough gels. The only active ingredient is the DXM. Last time, we drank a bottle each of a 4 oz maximum strength robitussian with it only having the dxm as active ingredient. We were wondering if the cough gels will make you want to throw up or not? The cough syrup did for myself and made me sick for about 2 days... maybe it was the sugar and taste... so will this be better on the stomach? Or was another ingredient in there that caused the reaction? Thanks!
