I think that exceedingly small is undercounting . I think we are letting our experience from the Western world where it is not as prevalent to drive our perception of the globe . Trousers in a genius ideal lol Indeed everyone can float with adequate flotation assistance . I doubt a trouser contraption will be enough for some of the worst body types . My goal is really to disabuse the notion that not being able to swim is just down to pyschological barriers . That ' s not always true . Some barriers are indeed physiological <| sep |> As for a little info about me , I ' m 60 , roughly 150 lbs and I think I ' m going to drop 100125 mg with maybe a smaller dosage later on in the evening . I suggest you stay close to 100 mg for your initial dose . Redose could be 4050 mg then . As for the comeup , the first time it was really intense and not exactly the most pleasurable experience . Copy paste from my 1 st time trip report Pretty much exactly 30 minutes in it hits me , hard . We made our way almost all the way to the front of the floor , therefore the most crowded area , and at first I noticed a shift in perception , as if everything I saw was very close to reality , but just slightly off . I also felt exceptionally lightweight , before all the sensations came in at once , which left me in an uberconfused state . I had difficulty keeping my balance and not bump into other people . Somebody touched my arm with his water bottle and I was surprised by how incrediby cold it felt . My friend was apparently going through a similar comeup . All of this only lasted for a few minutes though , and while it certainly didn ' t feel pleasant , it was still bearable , primarily because I knew this might happen and that the effects won ' t stay like this . Every time after that it has been very slow and gentle , sometimes even almost too subtle to notice and I would just realize at some point that something has been going on in my head for a few minutes already . Don ' t worry about it too much . It can be a pretty intense , almost harsh sensation , but it doesn ' t have to be . And even if it is , just try to stay calm , find a secluded spot , breathe , gather yourself and it will pass within a few minutes and you will be welcomed by a truckload of bliss
