I can feel your frustration, Jennifer, as I have had those moments in my Keto journey as well.
I had to do a lot of adjusting to figure out what worked for me and I think that is true for all of us, as all our bodies are different.
Personally, I had to eliminate all artificial sweeteners and most of dairy. (On special days like a holiday, etc I will still have a Keto sweetener treat but this is rare now). I still use Butter and a bit of cheese at times, but I had to totally get rid of my HWC and that was hard. I use a product that I buy at Costco that has a long shelf life (and only needs to be refrigerated after opening (then use container within a week).
Kirkland Signature Organic Fortified Almond Beverage -Vanilla Flavoured (yellow box, you get 6 for around $10). The ones I am working on at the moment do not expire until February 9th, 2021 and last for 1 week per carton so it is good value wise and works for me.
I use it in coffee, tea, herbal tea, and it is a good alternative for me.
We are all here to encourage you, I know getting to your goal can be frustrating at times, but you can do this! I wish you all the best =).
