My approach to using it is as follows. I usually apply a few drops behind each ear as we start our day. The package official directions state apply 5 minutes before your activity and apply as needed.
Then for rides, that I know will affect me (Tea cups, Everest - the backward motion is not my best friend) I add one or two more drops right before the ride. Another thing that I forgot to mention is that if you forget to apply or you do not have enough on (whatever that is) and you start feeling nauseous - take off the lid and take a nice deep inhale and the ill feelings dissipate within a minute or two. I personally love the smell, so this is not bad at all.
I think I may overdo the applications, but I would much rather play it safe than be sick for hours on end.
Last trip, I did my normal application before RnR, went through single rider (10 min wait or so total) three times in a row and never added more and never felt ill.
The bottle is small in size, but goes quite far. On a two week trip I usually still have some left, unless I forget to tighten the lid and it leaks. Yes, that happened a few times, but the side affect is I had a constant smell of it! LOL
Package state 20 applications per bottle, but I think you can get a few more than that. Also, remember back to back rides do not always require more. Most times an application will last hours for most rides.
I am hoping everyone has the same benefits as I do as it really changed my ride experiences and enjoyment as I now can share the thrill rides with my son again! I still rode them before, but then felt horrible for a good bit afterwards, now it is ride and enjoy.
I also appreciated not feeling drowsy or in a fog after use. Dramamine always put me to sleep.
If you have any other questions, just ask. From checking around
Walmart is the cheapest place to buy in our area, but that may vary.
Thanks and have a great trip.
