Xylimelts Sensitive
I was sensitive to the regular Xylimelts after a few months use. Painful gums and hives inside my lips and cheeks. The sensitive version immediately corrected the problem and I’ve been using them without issue for nearly a year. The product is a lifesaver for drymouth that occurred when I was sleeping.

Best that I have found for dry mouth.
These are the best for dry mouth at night. They mostly stay stuck. I say mostly because I have had a few come apart. I think that was my fault.

Business Breakthroughs Await: Unleash the Potential of "Who Not How" in Your Ventures!
Format: Kindle
The impact on business success is exponential for those implementing Dan Sullivan’s “Who Not How” model. The strategic framework presented in the book has fundamentally altered the way entrepreneurs navigate the challenges of running and growing their businesses. The model is a game-changer, shifting from the traditional “how” to the more effective “who.”
Below are a few key points:
Define Your Unique Value Proposition (UVP):
The model encourages businesses to articulate what sets them apart, fostering a deep understanding and effective communication of their unique value.
It provides guidance on identifying specific topics and themes that resonate most with the target customers, resulting in a more targeted and impactful approach.
Identify Key Tasks:
The book prompts entrepreneurs to compile a comprehensive list of tasks crucial for business operations and growth, including marketing, branding, and sales.
Categorize Tasks:
Categorizing tasks into areas of expertise, such as marketing, operations, content creation, and sales, clarifies resource allocation for optimal results.
Prioritize High-Impact Tasks:
The model assists in identifying tasks with the highest impact on business growth, such as creating compelling content, building a robust online presence, and securing motivated customers.
Identify “Whos”:
The transformative recommendation to identify experts or partners for specific tasks has proven beneficial. Hiring specialized individuals, like a virtual assistant for administrative tasks, a marketing expert for online promotion, and dedicated customer service, enhances efficiency and customer satisfaction.
Build a Team of Experts:
Assembling a team of individuals with complementary skills is a game-changer. Leveraging the efficiency of freelancers, agencies, and part-time professionals fulfills specific roles, contributing to overall business growth.
Dan Sullivan’s “Who Not How” model is more than just a book; it’s a strategic guide empowering businesses to leverage expertise and build a team capable of achieving remarkable results.
The book is highly recommended to fellow entrepreneurs seeking exponential business growth. ~ Linsey Mills
