I've heard that doses of 80-100mg would be toxic or cause someone my size (51kg) to fall asleep
I don't think that 80-100mg would be toxic, I have a source claiming that around 7mg per kg bodyweight would be dangerous for an adult.
But just to be safe better don't go over 80 for your first time, maybe up to 60mg now and report back
I'm going to go up to 108mg tomorrow (this isn't working I might just have low sensitivity) and it'll be around 1600mg APAP as well how bad is that for my liver if I just do it once
