6'1" it might be altitude sickness
To be honest if you are training in FL in a C150/152 its no wonder you are feeling ruff.
I was doing some hour building over there and after two weeks was on my way home.
Usual screw up with flights and I took $400 to take an alternative route.
Ended up in a TP heading down south to Miami bouncing around low level.
They started handing out food and I went for the salami bun thing. I was the only one eating. As soon as I opened up the packet and the smell wafted up the aircraft there was muttered swearing and the rustle of sick bags which then changed the smell to barf which triggered the rest of them off.
The hosties were very kind and gave me another three of them to take with me as I was on a German carrier next to be fed with that minging black bread and sauerkraut.
