Some people have to take extra hydrochloric acid (HCl). Some people have alterations in their gut/intestinal flora (microbiome).
At least one study cites where sucralose (Splenda and it's generics) alter the microbiome.
I would probably start by cutting out sucralose containing products.
I would then add a good probiotic.
Some use grapefruit seed extract and oil of oregano to help purge any fungal/amebhoid types of organisms. Obviously, one would want to space this from the probiotic since it might effectively diminish any benefit from the probiotic.
There are many sites that also advocate for using resistant starches to feed the good organisms in the microbiome.
Many Paleo sites have these discussion, but YMMV on what you're willing to incorporate or experiment with in your own personal ketogenic diet.

SF Red Bull appears to not use sucralose as a sweetener, so if it's that, it's likely the caffeine. I would do a taper of it over a few days to minimize any caffeine withdrawal symptoms (headaches, especially), then stay off of it for 10 days to see how it effects you before applying other 'fixes' like the probiotic.
Probiotics are a rabbit hole. Some people believe that soil-based, refrigerated probiotics are the best. Me? I just by probiotics with the highest strain count off the store shelf (not refrigerated) that I can afford. I try not to let perfect be the enemy of good enough.

Do one change at a time or you won't know which thing worked to solve your problem.

Keep me posted!

I do drink a lot of caffeine. I'm pretty sure it's slowing down weight loss too. The last couple night I haven't slept very well either. I love my fat coffee sooo much. I'll get rid of it and let you know how it goes. I'll do two cups a day for a couple days and then one. I think I'll find me some decaf caf tea for my coconut oil.

God, that's such a bummer. I loved my caffeine too and hated *so much* to see it go.
Also, I found that I can't do coconut oil after 5pm and still expect to sleep, so any coconut oil I ingest is done before that time or I'm pinging off the walls into the wee hours.
My understanding is that with ketogenic diets, serotonin can be effected as well. One of my friends here had good success with a melatonin supplement, so you might find that helpful if sleep is still an issue.

Yes I've been reading a lot about leaky gut and stress hormones and where is carried a lot of weight in my stomach I'm sure these are things I need to work on. Just when I think I understand everything I'm overwhelmed with information again. Lol I believe I'll look into that supplement. I've been stocking your food diary. Lol oh and by the way I know it's only been a day but I've had no heartburn. I only had a cup when I woke up and one after I took my son to school. I was so sad not having one while reading this afternoon but I survived.

Stalk away! That's why I have it open! Let me know if you have any questions.
I also have a blog here: http://www.myfitnesspal.com/blog/PatchEFog
I'm glad to hear that the heartburn is easing up. It can be miserable, and isn't so good for your throat/esophagus if acid is washing back up. It's actually not good for your teeth either.
