First time I have ever heard of Diazepam used for motion sickness. I cant remember what it was they had on the cruise ship that I had to give to the wifey (Sister and Brother in law who was ex Navy also took it) but it worked. Ive never been seasick a day in my life, heavy seas just makes me irritable from getting jostled around and not being able to sleep. I do use Diazepam for a sleep aid though. My fluctuating work schedule throws my sleep pattern off and if its gets pushed too far Ill go for days with no sleep and this is the only thing that worked. Went to a sleep study and ended up pulling the probes off my head and walking out after cursing the woman who was conducting it. She yelled at me saying that they couldn't do a sleep study if I didn't go to sleep. Look you stupid *&^%@$%&^*, I'm here because I CANT sleep! Tried everything on the market for sleep and none of it worked. One 10mg Diazepam and 30 minutes later I'm sawing logs! Had one female physician that gave me a hard time about it telling me its addicting and that I needed to find another profession. I threw it right back at her and her answer was that she had too much time invested in her profession...duh huh! I dont see how I am addicted as a 90 supply generally last me 6 months to a year. I only take it when I cant sleep.
Steer clear of the stogies when at sea. They seem to provoke a puke attack. When I was in the USN I was mean to the barfers, when I saw someone green around the gills I would stoke of one of the gnarly homemade sticks I picked up in Honduras for $2/100. Instant results! Had a chief that I still for the life of me couldn't figure out why he joined the navy let alone stayed in. That guy would start puking as soon as the mooring lines were cast off. Once when we were deployed they were running low on the patches and called everyone who depended on them down to sickbay so they could distribute what was left. He had the bawlz to come into my workspace to get me a ration of sh!t and made the mistake of leaving his box of patches on my desk. Needless to say that box went for a swim about halfway across the North Atlantinc in the winter, very rough seas. Some get it worse than others. When I went to meet my ship for the first time it was in the Mediterranean. I had to fly onto a carrier then catch a chopper to the destroyer. I went down a ladder on the carrier and there was a guy sitting on a 5 gal bucket with another in front of him sick as a dog. I asked what was wrong and he said he was seasick.....on a carrier! What makes that funny is when I left my ship 4 years later I flew off on a chopper to the same ship to be airlifted back to the states. Down the same ladder sat the same guy still puking into a bucket. I was like damn dude, you been sitting here puking for 4 years?
