Ironman Nutrion Problems

Hello, currently training for IMAZ, which is just around the corner, running into a problem for what to use for electrolytes when on bike. Yesterday in an olympic distance race (Lifetime Tempe Tri) on the cycling portion I used Hammer Perpetuem Strawberry Lemonade (2 scoops for around 2 hours) and Cliff Shots Mocha as well as Honey Stinger Strawberry Waffles. I think the Mocha Cliff Shots and Strawberry Perpetuem didn't settle well in my stomach and resulted in having to throw up twice during the run, and left me cramping throughout it. Throughout my training I've been using chocolate cherry cliff bars but recently switched up to mocha. I did a couple test runs with mocha as well as a long bike with the Hammer Pepetuem, not sure if I put them together. I weigh around 185 and try to get around 60 carbs per hour. I was thinking about just switching to salt tabs instead, because I've been using them in my long runs and they seem to be working out. (usually take 500mg per hour; not a salty sweater) Was just wondering what you guys use for your electrolyte source? I need to switch something up....
