Yes the uncontrolable shake in the leg (right rudder) first solo and after a long break or a different plane. Just ask Neil (Jaffa) how nervous I get. Neil would say "Relax Cozi". White knuckles on the stick. Deep breath.
One thing that helps me is what Icarus said above. Study the strength of the aircraft your flying avg +4, -2 at MTOW. Look at old Silverado at GOFLY, over 7000hrs last time I looked.
