DNF @ 50%. There were two fundamental obstacles for me:
1. The main character is supposedly an M.D., but I couldn't believe it. He sounds and thinks and acts like a 20-year old college student. He wasn't credible as a mature adult professional.
2. At least half of the text is filler. For example: We get treated to EVERY STEP involved in getting out of bed in the morning, walking to the shower, turning the water on for the shower, getting the towel in place for the shower, taking off clothing, getting into the shower, washing in the shower, getting out of the shower, walking to the bedroom, thinking about getting dressed, getting dressed, walking to the kitchen, looking at food options, getting out the dishes for breakfast, filling the breakfast dishes, operating the appliances, buttering the toast, spreading the marmalade, pouring the milk on the cereal, filling the mug with coffee, carrying the breakfast to the table, sitting down at the table, smelling the coffee, reacting to the smell of the coffee, drinking the coffee, reacting to the taste of the coffee... And we're not done yet, because there are STILL more details to be itemized (teeth must be brushed! hair must be combed!) before the MC can leave the house and start his day. Bored yet?
It's kind of a shame, because aside from an occasional clunky sentence, the author seems to have a good grip on the English language and successfully establishes a light, breezy tone. Self-publishing isn't doing her any favors; if she worked with an editor she could potentially tighten things up and take it to the next level.
But my bottom line is: Life is short -- Embrace the DNF.
