Congratulations! You've lost the equivalent of a person, that's amazing!
To get to 199 by July 4th would be about 1 1/2 pounds a week - you can definitely do it! Personally, I'm an every day weigher - I like to see even the smallest progress as affirmation of my hard work. I think you should do whatever works for you, though - this might be a great time to put the scale aside and focus on how you look and feel, rather than what the scale says. I'm seriously considering forgoing the scale for a few weeks for just that reason
And even if you don't completely meet your mini-goal, OMG, you should be so proud of yourself! My only advice is keep doing what you're doing, because you're doing great!!
