I'm not proud of it at all but I've ended up in hospital probably about 3-4 times from taking too much G. When I think back to it now, I cringe at how stupid I was. But in saying that, a couple of times, at least, I feel like it hasn't been my fault. Once I was at a major dance party in melb. Got my G from my source, had a charge at 6pm (2ml or so) prior to going out. Then maybe another at around 9ish, then once I was at the venue, which was around 11:30pm) I had another around 1.5-2ml. You may be thinking that my charges were too close together or I'm not experienced enough to tell, but the thing is I know my body well with G and the other times I had G'd out it was my own fault. This time I was careful and took it slow and I still G'd out, not bad, but enough for the security to notice and they got an ambo etc etc..
So to my point... I believe G, at times, can be very unpredicable. Some days you can G out a hell of a lot easier than others, even when the stregth of your G is the same. Even after that, G is my most favourite drug to take (with meth) while going out. The absolute freedom (socially) it gives me is awesome.
