Why Sugar Tax Is Bad For Diabetics

In Ireland there is a new sugar tax in a bid to combat an obesity epidemic. I won't delve into the politics of that side of things. I just want to say why, in one way, I think it's a bad thing for type 1 diabetics.
In order to seem healthier soft drinks manufacturers have been selling 'diet' drinks with artificial sweeteners to lower the calorie count for years. Now that sugar has a worse reputation than calories and fat these sweeteners have been creeping into mainstream soft drinks. The main one is aspartame. In a lot of labels where this sweetener is listed as an ingredient it is followed by "contains a source of phenylalinine. Over consumption may cause a laxative effect". Not something you want to be consuming if your gut has been damaged by coeliac disease and you struggle with ibs if you eat the wrong food. I have also read reports on studies that suggest artificial sweeteners might be inflammatory and trigger an autoimmune response. They are certainly a no no for the autoimmune protocol diet. They confuse the body because when you taste the sweetness it primes the body to be ready for sugar but the spike in glucose and energy never comes. I have found that I need to pee a lot more when I drink stuff with aspartame in it and I cannot stray too far from a toilet if I drink too much, so I avoid it altogether now.
When I was small Lucozade was a fizzy drink you gave to sick people. It crept into the mainstream soft drinks market more and more as I grew up as energy drinks started to take off. My brother has almost twenty years experience with diabetes and it is his go to option when he goes hypoglycemic. In recent years the recipe has changed. The amount of glucose has decreased and aspartame has been added. It still has plenty kick to get you out of a hypo but I'd rather not consume it at all now that aspartame is in it. Would it not be possible to make the original recipe available to be sold alongside their glucose tablets in pharmacies and health food shops without the sugar tax? Why should diabetics be victims of the sugar tax everytime they go hypoglycemic?
