Realizing I have an addiction

A little over a year ago after years of yo-yo dieting along with bulimia, I made the decision to get control of my health and enlisted a personal trainer to get me on track to be the best ever for my 30th birthday. Long story short, she completely turned my diet upside down and had me incorporate a lot of lean proteins into 5-7 small meals per day. This coupled with exercise returned HUGE results not only physically but emotionally and mentally. I had more energy. I stopped binging, and I was on-fire in all aspects of my life.

Fast forward 9 months my strict diet had relaxed a bit, but I had sustained the results and decided to take it to the next level and prepare for a fitness competition. To achieve the necessary physique, I have to be on a very low carb and high protein diet. Though I knew the restrictive diet would be difficult, I didn't realize my degree of sugar sensitivity and the detox of going from a healthy diet with a few high sugar cheats to a completely clean and low carb diet. I couldn't focus on anything. I couldn't sleep, I was constantly anxious, and I felt like a failure and that nothing was possible. My productivity at work was zero. I wasn't my usual happy self, and I started binging and purging. Thankfully I caught myself before I spiral to far and remembered the PnP book that I had bought years earlier that I never got around to reading. Within 2 pages, everything clicked. All the struggles for so many years. My depression and even how my change last year became so easy after only a few weeks on the new diet.

So I'm here looking for support and suggestions. Because of my previous changes I've already made it partly through a few steps (1,3,5). I'm working on incorporating emotional and physical feelings into my existing food journal, which is going to be really insightful. However with my training, I feel like I've zoomed to step 6, and I'm struggling with the fall out.

Are there any recommendations on supplements to help with the detox? What are some no to low calorie substitutes people use when faced with a craving for sugar? Is there anyone else out there trying to do a bikini or figure competition?

Sorry for the long post, but anything even just a hi would go a long way to making me feel like I'm not alone.
