I keep trying for new products and I send them ideas regularly. I am trying to get them to consider a "Mix a Mousse" product like they have there in the UK so we can convert our shakes in to a pudding. I am also trying for a Malt flavor shake. Our company is a lot smaller then the UK and new product development is very expensive. Production is also a lot more since the manufactures we use charge more for smaller lots. I keep firing off ideas though! lol! feel free to do the same. You can contact them direct and make suggestions.
Also...you are SOOO RIGHT! the trick is exactly that. Don't let a slip turn in to a slide. Get right back on track, make yourself a shake, and tell yourself you are back on your diet. Just keep going
