Welcome to the forum, William.
In order for us to give you more helpful advice, could you please let us know your age, height, and what you are eating?
Basics of Keto are 20 grams or less of Carbs, NO Sugar (for some of this is also includes no sugar substitutes), adequate proteins and healthy fats, drink enough water, and get enough Electrolytes (salt) so that you can avoid cramps, and feeling really achy.
I use cronometer.com to keep track of my macros and it helps a lot, to make sure that I am sticking below the carb level daily =).
I started Keto in February at 293 pounds, and I am now 242 pounds (I have lost 51 pounds so far). My goal is probably somewhere around 120, so I have a long way to go, and I am expecting that to take probably abut 2 years or more, to be realistic. Slow and steady wins the race, and this is not a diet, it is a life style WOE (way of eating) change. If you think of it like that; and rejoice in all the NSV (non scale victories) that you will be able to celebrate along the way with your weight loss, you will love Keto as much as we all do!
My blood pressure was extremely high (my doctor was about to put me on BP meds, but I got it down quickly with Keto and avoided that!). Aches and pains will significantly diminish over time, as will all cravings for sugar and carbage, you will have more energy, and your skin will improve, your body will shrink, your self esteem and mood swings will improve, and you will feel healthier and happier!!
You have found the most supportive, friendliest and amazing forum on the net, so that is one victory for you already.
So; again, welcome, and just be patient and Keto on =).
