6 weeks and starving all the time....

So Sunday night I was insatiably hungry. I woke up twice and ate a piece of peanut butter toast each time. Decided to skip my toast for breakfast Monday morning and nearly crashed from low blood sugar when I got to work. I was literally starving all day at work even after eating my usual lunch and snacks. Does this hunger lessen at all after the first trimester? I really dont want to put on a ton of extra weight. Lol. What healthy snacks do most of you eat to curb the appetite?
