in regards to the motion sickness let me just say that i do not know anyone who suffers more than myslef. i get sick in all forms of enclosed transport: planes, cars, buses, trains. in my one attempt on diving i got sick without even being on a boat, just floating on the surface made me green. during haiti earthquake i nearly lost my breakfast and had to sit down for a while before my stomach settled down.
i also cannot play computer games that require complicated movement: those futuristic shooting games with aliens jumping on you from the ceiling and the player "looking" in all direction? puke. i cannot see videos with too much movement, cannot even watch people spinning around, let alone do a pirouette myself.
when miesposo parks the car backwards i have to get out first. i do not park backwards myself, i do not even drive back except the few meters it takes me to back up the car out of the driveway.
i know it is all about the inner ear thingy, yes. and yes, i have the poorest balance you'd ever see. cannot skate or ski and i only learnt how to ride a bike when i was about 12.
what else...? let me think... cannot do bouncy castles or trampolines. no swings of any kind. and i am sure i am missing other things here...
transdermal scopolamine patches available in DR? They are by far the most effective think I know for motion sickness, you even see Coast Guardsmen wearing them
