Use to use them a lot, but as I get older, I just take my time and do the work because I have serious cramping issues. I kept plenty hydrated, but it took me a few weeks of strange cramping in non-standard areas to get my electrolytes all in order with high dose potassium, magnesium, and B. I was using them in a borderline ketosis state, and it was just too much at this point to mess with. Just not worth the trouble to expedite a process that was already working fine. I miss them though, as I always responded well to them, and god knows none of us are great at delaying gratification around here. I may check out that product linked, since it specifically said it didn't have cramping as a side.
