I notice that your gains are every 3 or 4 weeks after you marked your * week - I wonder if that is causing a load of water retention ... indeed, week 3 is also in this pattern and is a much smaller loss than the weeks around it. It could be that the TOTM is 'telling' you to snack - if this is the case, it might be easier to prepare for it next time ..
Please try not to feel disappointed in yourself, you have had a great weight loss, and a blip here or there is just that - only a blip, not a failure - just try and take it one day at a time - have lots of 'allowed' snacks at the ready, and try to remember why you started this journey - it might give you the motivation you need to get yourself back on track.
take care xx
