Then switch to Lizzi's when you've finished it.
I found a huge difference, between Lizzi's, Dorset Cereals and Jordans.
Lizzi's is fabulous, much better than the Dorset Cereals, who had changed their recipe. Then I found out why ..... Dorset Cereals had also been bought up by the same sugar giant who owned Jordans.
There really is a massive difference between Lizzi's and all the others.
I also found that Alpro Almond milk unsweetened made a big difference to my BG readings. I keep a carton in the fridge door, just for my brekkie.
