sharp pain in my head during session, pounding headache afterwards, dry mouth so my tongue sticks to my mouth, sweating, flushing, dizziness, zoning out, unable to focus or concentrate, hyper-awareness of my whole body or any particular part of it, i play with my shoes (foot up on one leg), shoelaces, anything on my coat which i always wrap around my waist even though my T always asks if i want to hang it up, play with my watch or fingers/hands and often catch myself doing all that fiddling with things without even realising ive been doing it.
so no you re not alone.
