Hi Sooze - I didn't like a lot of the packets or bars either, mostly had the drinks, made into thick shakes. I made muffins/pancakes once in a while. Only bar I liked was the choc/coconut one. I was strictly IP for probably the 3/4 of the time, then in the last few months added in some alternatives like Quest and Proti-thin, partly for the variety, partly for the $$$. I honestly don't know if having just the lower carb options makes a difference, I have seen people post who have done that and have stalls and low losses, and do better when they add in a restricted or extra packet. I think it's individual, and trial-and-error for each of us.
But, like HIS said, your average loss so far is really good, so don't stress, it will work.
So sorry about your foot, that makes it hard. Hope it heals quickly

But if you have access to a pool, maybe you could swim if you can get your foot wet, or some water exercises.
