Good beverage choice to mix your colonoscopy prep powder in.
Flavor Name: Kiwi Strawberry, Size: 16.9 Fl Oz (Pack of 12)
In preparation for a colonoscopy I was allowed to mix the required prep powder in any flavored water beverage that replenishes electrolytes as long as the color was clear. I dislike water and am not good at drinking the daily minimum requirement. I had to find something I could tolerate especially with my having to drink 64 ounces in a matter of a few hours. So I started my Amazon search and based on the reviews, I purchased both the Propel Strawberry-Kiwi and the Melon flavors. I was taking a chance that at least one of the two flavors would work for me. The Strawberry-Kiwi albeit on the sweet side surprisingly tasted good after I added a ton of ice and made slushes. I really didn’t taste the Kiwi but the strawberry came through. The melon was less sweet but I did not get a real taste of melon flavor, just a hint. Since I only needed 64 ounces and each bottle is 16 oz, I only had to use 4 of the 24 bottles I purchased leaving me with 20. I’m going to continue making slushes but plan on adding fresh strawberries and melon to the mix and this way hopefully drink more while getting electrolytes. One Amazon review I read was by a couple who drank Propel daily and really felt sluggish if they skipped a day. I am hoping that by the end of consuming 20 bottles, I will also see a difference in my energy levels. The cost of Propel was extremely reasonable compared to like brands that in my opinion weren’t any different except for price. Even though Propel is sugar free, it does contain sucralose. As a I diabetic, I am not supposed to have any sugar substitutes other than stevia, but since sucralose is not one of the primary ingredients, and pretty far down the ingredient list, those 64 ounces I drank had a minimal (if any) effect on my blood sugar.

A standard item in my house. I have trouble swallowing plain bottled water and Propel is THE BEST. I especially like the Kiwi Strawberry flavor.

LAVAZZA
Flavor Name: Espresso, Size: 35.2 Ounce (Pack of 1)
This is my go-to coffee for a smooth, rich espresso every morning. The medium roast has a perfect balance without any bitter aftertaste. Since they are whole beans, the freshness and aroma are top-notch once ground. It’s a great value for a high-quality 100% Arabica blend!
