Night time

Does anyone else get random bouts of nausea that wake them up in the middle of the night for no apparent reason?

Im currently on holiday in France and got woken up at 1:24am by intense nausea. Not like im going to v*, but damn close. This hasn't happened in weeks now, and Seabands, Cyclizine and Polo Mints seem to somewhat help, but its still hard to live with.
