It’s very easy to overdose on G. When people overdose they might sweat a lot, have fits, and lose consciousness. Overdoses can be fatal
Combined with alcohol, G is even more dangerous because it is also a depressant like alcohol. This means the combination inhibits the liver's ability to metabolise the G.
