Overdose of Strepsils?!

I've had this excruciating sore throat for a few days now. My mum has attempted on many occasions to give me this really disgusting medicine. Its meant to cure the sore throat but its so gross that I throw up every time I take it. My mum told me to take some Strepsils, you know, those sore throat/cough sweets if I really didn't want to take the gross medicine. So now I've gotten a bit addicted to the strawberry ones. The packet says take one every 2 hours but I've been taking about 10 a day. They taste so good, I can't really help it. They actually do help my throat though.. I know I've taken way too many, and now I'm very worried. Are there any major ingredients in a Strepsil that could potentially be serious to my health if I've taken too many? What's the worst that could happen?
