Motion sickness

[Lucca]

As it is in almost every situation in life, there is a cost / benefit balance to be made. I would be very happy not having to take anything and simply not to care about motion on the boat, but it seems my body doesn't agree with that. Scopolamine is serious stuff but motion sickness is simply unbearable and almost suicidal for some people (I, one of them). I tried and read "anything and everything" for years and in the end it was Scopace what worked wonderfully for me with no apparent side effects and without loosing concentration or attention while diving (even the lab's name is "Hope" ). Try Scopace at home first because it's not good for everybody.The placebo effect, the cognitive techniques, and so on may be true and work for many people... not for me. Letting a sick person pilot the boat is good advice; not enough in very rough seas though.

For the record, that is dangerous as there is a risk of inhaling water. Puking thru the reg then purging is safer. Hold breath and rinse once control is established, repurge and go.

I do gas drills the Padi way anyway. The Octo is cleaner in all cases.

To each their own, Don; I make my own choices.

I tried to word that in a way as to not seem to criticize your choice but still suggest to others that it is a risky choice. Sorry if I failed. :blush:

I'm told:

Scopolamine has the same chemical formula as cocaine -- C17 H21 NO4.

It is also the original "Truth Serum"

This trivia is true, but I can see how such information might be misleading. The chemical formulae are identical, but every chemist/biologist knows that chemical structure determines function. Although the chemical structures are reminiscent of one another (ester off of a piperidine-like structure), there are enough differences to suspect very different functionality. Many studies have demonstrated that the molecules act in different ways on completely different structures. Cocaine blocks reuptake of monoamine neurotransmitters (5-HT, NE, DA) at presynaptic sites. This effectively increases concentrations of those neurotransmitters in the synaptic cleft. On the other hand, scopolamine acts as a competitive antagonist at muscarinic acetylcholine receptors. Essentially, scopolamine turns "OFF" downstream acetylcholine-based neurotransmission.

FWIW, I think that any drug which acts as a hypnotic or anesthetic could be used as a "truth serum." It's thought that the drug will remove any inhibitions the subject might have. If I were a CIA operative interested in interrogating someone, I don't think I'd select a truth serum agent that, when administered orally/parentally at the high doses necessary to work as a hypnotic, could have such profound physiological effects that it might kill the interrogation subject.

Disgustingly, I am good enough at it to pull my reg, urp, and replace it. Never messed in a reg.

Thought I'd share in case someone thought twice . . .

OK then, duely noted.

That explains why my last dive with my girlfriend was my LAST dive with my girlfriend.:depressed:

There is no research evidence of which I am aware to suggest that significant tolerance to the anti-motion sickness effects of usual doses scopalomine would be anticipated when taken "regularly for years" for day trips or whole weekend liveaboards.

Nevertheless, there is anecdotal evidence of which I am aware to suggest that significant tolerance to the anti-motion sickness effects of usual doses scopalomine with a history of being taken "regularly for years" for day trips or whole weekend liveaboards. Motion Sickness

Now THAT's scary!!

Oh, well! Just picked up scopalomine patches. I'm wearing one though the weekend to make sure I don't have side affects, and then I'll give it a try on the boat.

I will call, "Success!", on anything that keeps me from urping more than four times . . . . (how's that for a standard? )

If the individual given the rod with a sailfish on the line was told that this would cure his mal de mer, and it did, that could be contrued as a placebo effect.

If the individual was simply given the rod with a sailfish on the line and his mal de mer resolved, the responsible psychological mechansim would be contrued as a function of diversion of attention or the like.
