Working Out in the morning — what am I doing wrong?

Hey everyone,

I want to do my workout in the mornings—it works so much better with my schedule. However, every time I do, my workout ends with me either being super dizzy or even throwing up (mostly water)... it’s not fun. This has happened multiple times. If I do the same workout (same intensity) in the evening, I am completely fine. But I really want to do it in the morning.

What is the secret here? Do I need to drink water and have a spoon of peanut butter before bed or something?

One time, I tried having a small snack right before (a breakfast bar), and that helped... but I don’t really like doing that because I feel like that offsets my calorie-burning whereas, if I workout in the evening, I don’t have to have that extra little snack... is there something I’m missing??

By the way, I do both cardio and weights. Sometimes a P90x dvd at home.

Thanks for your help!!
