It sounds like you're dying. If you're reading this, you should go to the ER right now so you don't die.
Seriously, there's some leg work you'll need to do for your diet. 1) Read Rip's "A Clarification" article. 2) Read my "To be a beast" article. 3) Understand that you're not supposed to just add a gallon of milk a day to your diet overnight. You'll have issues dealing with all the extra calories unless you titrate it up- this is especially true if you're not a big dairy person prior to this. Starting at 2-3 glasses of milk per day and adding a glass every 2nd day until you're at a gallon is reasonable, but then again you might not need GOMAD if you're eating enough calories otherwise to gain weight (you do). You're massively underweight and given your 'stall' point, I assume you started too high weight wise, form was not very good, and you haven't been gaining weight - probably in addition to not sleeping well either. You might consider reading this too. Chill out though man, you're just rushing the process. Start over on Monday and get your shit together over the weekend.
