Yes - I absolutely know what you are talking about!! When I had my sleep study several years ago - they told me I was waking up more than 100 times per night - I couldn't believe it. So - I sleep with Pappy now...(my CPAP) and it only took about 2 nights to get used to the mask and hose. After that - can't sleep without it. And I love to crawl under the covers in my Bed Bath and Beyond "Beech" sheets which are sort of like T-shirt sheets except they feel like a million bucks. I first slept in them at my niece's house and OMg, I was amazed. So - now that I love getting a good nights sleep with Pappy...I just had to have those sheets too!
I can also relate to the excitement of your upcoming surgery. I have 43 days to being sleeved. Sigh... I talk about it to my daughters, and I can barely focus at work because I am so HAPPY to never have to be on yo-yo diets again.
My insurance doesn't cover so I decided to self pay in Mexico ($4500) and most people are saying their out-of-pocket was at least that much. Plus I don't have to go through all of those tests ahead of time. I'm glad and I've met such great people on this website. People that understand completely what it's like to suffer the "looks" and comments related to obesity.
Bless you and good luck. Full steam ahead! Reb
