Jubilee - I want to also offer my support to you. As you know, I'm facing some kidney issues also, not fun. Like you, I know that eating SAD isn't responsible for this issue, but eating well should help us have the strength to get through our respective surgeries/procedures, etc.
Having said that - this past week was not my best with food. I definitely gave in to temptation more than once

between Easter candy and hubby wanting to eat out several times. Let's just say his idea of a great meal is the complete opposite of McDougalling. Lest you think I am not telling the truth - he said after the meal last evening "This is a great place! They give you the salad and those pesky veggies of front so you can be done with them after a couple of bites, then get to on unlimited meat!"
This morning I stepped on the scales - very grudgingly. I felt like a little child about to be reprimanded for misbehaving, knowing full well by how I feel that the numbers would be up. I don't know if this will make sense, but it was another round of knowing that I had messed up and this feeling of Satan just back there laughing and taunting "See, you couldn't keep up, you couldn't leave that stuff alone, what a wimp!" Yet again, facing that I can't do this alone. Honestly, if I lived alone I think it would be so much easier - not that I would give up my family though! But facing junk at every turn can be wearing.... I will be repeating "I can do all things through Christ who strengthens me" over and over, and I need to go back to my Lenten sacrifice of no food after supper. Evening is my weak time, no doubt about it.
Time to get back to work.
