Starting with the Boise 70.3 I tried out EFS energy drink (yes, I do mean the first time I used it was on a race day–I know, I know, bad idea). I had some gastrointestinal issues that day, but nothing too big. Just some knots in my stomach, and I felt like if I drank any more I would puke. But I didn’t puke, and I thought the reason I couldn’t drink any more was because I didn’t need any more. In retrospect, I’m wondering if I should have been drinking more, but couldn’t because the EFS was harsh on my tummy. But I only came to this thought because as I’ve been drinking it more and more, I seem to be noticing a correlation between a tight stomach and EFS. Again, it’s not that bad, and I’ve never had that “I’m going to throw up if I drink anymore” feeling (I’ve also never made it as goopy as I did for Boise), but the more I drink it, the more tight the correlation seems to be such that I’m thinking there is a cause and effect situation going on.
Other than that, it tastes fine (very subtle, mild flavors), and seems to work fine as an energy source. But if I continue to have the knotted up stomach, I’m going to have to switch back to Heed or something new.
Hey Josh, I use EFS drink and liquid shot and love it. I think it absorbs more easily than any other product I’ve tried. For the longer events I’m training for it’s fantasic. I don’t plan to eat anything else for 10+ hours at lotoja.
It’s funny, normally I have an iron stomach (no pun intended) but EFS seems to be hard on me. I’m going to start paying more attention and see how strong the correlation is.
My wife’s trainer swears by this stuff but I haven’t gotten around to buying any yet. Sounds like you know your business, so I’ll give it a go.
Thanks,
