Doing it wrong?

Hello my name is Eric and I’m tryin to be healthier and thought Cirkul would be a great start.

I took everything out of the packages and screwed the top of the bottle into the bottle and the flavour thing onto the top of the bottle. I went to get a drink and it feels like I’m sucking a pea through a straw. So I unscrewed the top of the bottle a little and still nothing more. I unscrewed it even more and the water splashed on my face.

Hmmm so I go online and find that little clear plastic nub sometimes gives people problems so I took it out and reset it into place and still the same problem. The only way this bottle seems to work at all is if I remove the clear plastic nub thing and drink the water with my finger over the air hole.

What am I doing wrong people? Am I really that dumb I can’t fix this? Haha
