Oh no they suggested sticking to the diet but just having one small glass of wine. I knew there was no way i would stick to a glass of wine so I wanted to make sure I was out of ketosis before I started drinking. It was easy getting back on the diet mind, no headaches or that horrible first few days feeling (when my hangover went that is!) I dont reccomend what I did tho just saying it was the best for me! Good luck with it xx
