Ok basically the other day I had a really bad cold so I took about 7 Tusso-DMR's which were cold medicines. After an hour after taking it, I slowly started to feel weak, then I knew I had to lay down and I got up and went out of the class into the hallway and my heart started pounding.. I was having trouble breathing. Then I eventually threw up and slowly started to calm down to normal. What happened? What would happen if I took double that?

Are you trying to hurt yourself?
It sounds like it .
What's the deal,why would you want to harm yourself?
Talk!

I wasn't trying to hurt myself but I simply had a bad cold and I didn't know that would happen. I was pretty scared less. Could I have died

You didn't so it's a moot point.
Don't ever be foolish with drugs.
They may not kill you but just make you messed up forever.

your body oviously had a bad reaction to them and yes your health could have got worse if you had taken a higher dosage. Everybodys body works different I would advise you not to take so much next time!
hope your feeling better =)
