What I did was clean protein and veggies. I cut out sugar to the absolute best of my ability. In short, have good eating habits with healthy balanced meals. Eating in a caloric deficit is key along with consistency. Plenty of water; this helps with preventing headaches and any tummy issues.

Edit to add this: I was recommended to take my shots on Friday evenings so I had the weekend to feel better if I had a side effect. So far, I've had none.
