Trying to give up soda switched to sparkling water that has no calories but has sucralose. is that as bad as sugar? trying to keep glucose levels low

As bad a sugar?: Sucralose is an artificial sweetener and in today's world, every artificial food additive will have people on the internet telling you that it's a terrible poison and the cause of most ill-health. I'd urge you to enjoy your soda and be glad that you're not getting a lot of calories to make you fat. How about instead getting a bottle of water and going for a good run?
