Oxygen not effective and cycle changing?

[Seattle cluster]

I didn’t realize this thread kept going   My cycle must have ended because when it does I try to forget all about these   I didn’t realize there were so many different size tanks and am grateful the VA gives me an M tank just wish I had one of my old oxygen companies  I just mentioned in my post that I bought that mask but never had a chance to use it until this cycle   I definitely think it has made a difference  I just had my tank replaced and finally got to experience what I have seen you guys speak about as far as the bottom of the tank being less effective   I actually think it messed me up more than if I didn’t use it but who knows   Someone mentioned Red Bull/ caffeine I tried it a few times didn’t seem to work that much but last time I slammed a sugar free 5 hour energy to abort an attack it sent me in to maybe the worst one I ever had to where I was actually throwing up from pain so not trying that anymore

Thank you for this post.  I think there have been a couple of reports in the past about energy drinks/shots making things worse .... sorry that happened to you.

...yup, nothing is a given in this CH battle....energy drinks work for many but no guarantee...at least you tried! one note on sugar free versions....many contain aspartame as sweetener...its an amino acid like msg, which are vasoactive and if causing dilation exactly the opposite of what we need. trial and error got me to sucralose as the artificial sweetener which caused me no problems...
