You may have had enough to drink - depending on the conditions, how hot it was, how much you were sweating this may have been enough liquid - but it definitely sounds like you were not eating - and for some people (me included!) a lot of liquid without solids = sloshing stomach = nausea. It's like getting seasick without having to get on a boat... combine that with some bonking (which it totally sounds like also happened to you - shaking and nausea) and you've a recipe for feeling really sick. It unfortunately builds on itself too - drink too much, start feeling sick, don't want to eat, get even sicker...

Don't beat yourself up - finding your perfect ride nutrition can be difficult and everyone bonks some time.
