Yep this sounds familiar. The first 1 to 2 weeks are the toughest. Eat when you’re hungry. Don’t worry about cutting outs snacking until you don’t get hungry between meals. I used avocados, sliced cucumbers drenched in blue cheese dressing, olives, Tillamoos cheese snacks, string cheese, Baby Bel cheese snacks, pepperoni, sliced ham spread with cream cheese roll-ups, pork rinds (sometimes spread with cream cheese), tuna (or chicken or egg) salad with lots of mayo and flavorful add ins (like diced pickles, green olives, sharp cheddar chunks, celery or water chestnuts - for crunch, hot sauce or Dijon mustard), etc… I was hungry all the time for those first couple of weeks. It eases off and finally goes away as your body adapts to using fat for energy production (fat from your food and fat from your body).
Also, drink plenty of water. Supplement electrolytes (google ketoaide recipes, or search here on the forum).
Good luck! And keep us posted. We’ll all be rooting for you
