- 初めての使用時はいきなり深い深度(-30m以上)まで潜らずにフィット感を試しながら徐々に深度を伸ばすようにしてください。
- マスクのフィット感、ストラップの締め具合がキツすぎる等、体調が優れない場合、スキル状況によっては浅い深度においてもマスクスクイズ(水圧の影響でマスクが顔に押し付けられること)や耳抜きがしづらい事象が起きる可能性がございます。マスクブロー(鼻から息を吐いて押し付けられたマスクを元に戻すこと)を行ってもマスクスクイズが解消されない、耳抜きをしようとしてもできずに無理をし潜行を続けると、眼の内出血、鼻血、頭痛、鼓膜の炎症・裂孔等を引き起こす恐れがあります。異変を感じたら直ちにダイビングを中止し、状況によっては医師の指示を仰ぐようお願い致します。
- 使用後は真水で洗い直射日光を避け、すぐに干すようにしてください。

Healthy, Effective, and great when mixed with Splenda and Koolaid mix. The best of many options I've tried.
Flavor Name: Unflavored, Size: 1.46 Pound (Pack of 1)
I've sampled a few different varieties of fiber supplements, including both Benefiber and off-brands, and I found that Metamucil provided the most fiber in the least offensive beverage. Compared to the other brands, this stuff is smoother textured, and goes down easier, as a sort of happy medium between the grittier supplements and the thicker ones.
What about effectiveness? I have apocalyptic IBS, and since starting to take this stuff regularly (one giant glass every morning and evening), my BMs have been much more regular, and more manageable. Flare-ups happen less, and it even seems to do a decent job when taken with meals of cutting the hit to my stomach and gut. I tend to take more than the recommended amount, with an even larger serving of water, as I feel like it helps me stay hydrated and full throughout the day.
I started taking the classic orange Metamucil, but although I really liked the superior flavor (rather like Orange Tang) it packed several times more sugar in each serving than fiber, so while it was great for digestive health, the overall health impact was too negative. I also sampled the sugar-free berry flavors, but found that, although it was ostensibly healthier, the flavor wasn't great, and in addition it suffered from the aspartame aftertaste and further effects (Aspartame gives me headaches). So this was a dilemma for me. What to do? I actually wrote to Metamucil about it, and they recommended this product. The downside is that it comes with absolutely no flavor, so you need to provide your own in order to mask the texture (I wouldn't dream of trying to mix this in plain water--yuck!) The upside is they pack 100+ servings into a container, and you really are free to blend it into whatever suits your fancy. Obviously if you mix it with something like orange juice, then you're already negating the benefits of this stuff over the sugary orange flavor, but I've personally found a much better way.
I like to mix this stuff with Kool-aid mix and Splenda (Sucralose) sweetener. I buy a ton of Splenda and kool-aid as it mixes up tasting sweet, like sugar, but without the calories or aftertaste. You can dump a spoonful of this stuff into a glass of splenda-koolaid, or just dump 8 servings worth of this stuff in with a packet of koolaid powder and a cup of splenda, and then just mix it up and spoon it into water as needed. Better tasting, sugar-free and packed with good useful fiber.
EDIT: I wish I could subscribe to this stuff. Price of splenda has gone up, but I've figured out thatyou can just dump 7 packets of koolaid mix and 7 dashes of sucralose into a container of this and shake it up.

#1 for #2's
Flavor Name: Unflavored, Size: 1.46 Pound (Pack of 1)
I like the lack of sweeteners and flavor. I just want the stuff that helps me poop. There is some citric acid in it (no idea why) which gives it a mildly acidic taste. Other than that, it does the trick.

Good Stuff
Flavor Name: Unflavored, Size: 1.46 Pound (Pack of 1)
If you need more fiber in your diet, you need this. The price is right, it works very well and keeps me regular. I use this instead of the gummies or capsules. That's because you MUST put in in fluid, and hydration is SO important when using a psyllium product as it causes water to be absorbed very quickly once it is ingested, and you don't want to dehydrate! Mixes very well in water and has little to no taste whatsoever. Stay regular, stay hydrated and stay well.

Works well, but is now too expensive...
Flavor Name: Unflavored, Size: 1.46 Pound (Pack of 1)
The "No added sweeteners" has been my go-to version of Metamucil, but I'm giving it 4 stars and moving on to another brand as the price is over $35 which is too much imo...

I like the mildly tart taste of this unflavored, unsweetened drink made up with water.
Flavor Name: Unflavored, Size: 1.46 Pound (Pack of 1)
I like the mildly tart taste of this unflavored, unsweetened drink made up with water. The texture doesn't bother me, with stirring right from the beginning of adding the water, there is no clumping. After 10 days there is no effect on my bowels which were regular previously anyway. My doctor wanted me to use this although I already have a high fiber diet.
