New to Keto. Just started Monday

Hello I am a 48 yr old female new to Keto. I just started on Monday and I am taking the Ketoligic MRP and BHB drink much to assist. Although it's pricy, I am disgusted that I am starting over again. I want to lose 65 lbs and appreciate any feedback, especially substitutes for a sweet tooth. Thanks in advance for your support! :)
