Gravol is Dimenhydrinate
In the US it is Dramamine. This was taken from the Alberta health services website. It didn't say it would kill you unless overdosed but it doesn't sound too fun to me!!!
Hope this helps

Chronic heavy users report problems with depression, confusion, loss of energy, vomiting, urine retention, and difficulty thinking and socializing.
Gravol and Addiction
Chronic use of dimenhydrinate can result in tolerance, dependence and withdrawal.
If you use this drug for more than a few days, you can develop tolerance to it. You will need to take larger doses to feel the same effects.
When dependent users stop taking Gravol, they experience withdrawal symptoms such as excitability, weakness and discomfort, poor appetite, stomach cramps and nausea.
are you using it as a sleep aid?? I used to do that too, don't think it's a good idea.
I just looked it up on wikipedia...you should too. Doesn't sound like a good idea.
