“I LOVE HELLO! It’s such a natural feeling energy boost and there’s no crash and no jitters! They work great! But unfortunately Goodbye triggers my migraines and they are some of the most intense excruciating migraines I had ever felt! So there’s no way I’m paying for something I can’t take but that means I won’t be able to order the Hello either.... ugh which is really frustrating because it did help so much!”
