11 days out and whenever I swallow I get this sharp tight pain in my chest almost like when u drink very strong carbonation , it only lasts a few seconds , but very painful! Anyone else experience this?

Try sipping. And spacing the sips. I get the same thing also. So I just rest a minute in between. Or I will drink something warm and it seems to help.

I did I think I was drinking too fast but eventually it went away I though I was having a heart attack every time.

Yes I went through it too it will get better overtime and your body is trying to get used to the new pouch...

Yes it feels like I'm having a heart attack. Thx ladies !!

Aww yeah thats cause of all your organs being close to each other and u being swallon in the beginning but you will be just fine good luck????

Try walking around when you get that way, it'll help release the gas pressure
