A few things i've done at points in my life where I"ve realized my diet needed a revamp(always been diff problem areas).. i'm in the craving sweets, junk, breads phase right now so need to ditch those..especially since hubby is diabetic and 1 daughter has celiac disease having those things around is just hard on the family.
Anyway..
....whenever i want to snack, I drink a BIG glass of water, like 16oz or higher, preferebly with ice the smaller the better... it hydrates you obviously, fills your stomach up some and the ice gives you something to chew or suck on, aleviating the "need" to process something in your mouth.(most of the time that you need a drink, your body sends a message, i'm hungry so chances are tthe drink will satisfy anyway)
.....cutting up a apple, especially a crunchy one(granny smith for example) into small pieces, put in a cup/bowl on the counter, as you are walking by and "gotta munch" grab 1-2 pieces(walk away), eat one at a time and chew it completely, aim for 30 times. you're mouth will be happy to be busy, you get sweet you get crunchy and it will last you the whole afternoon and give you around 100 calories, which you probably burned chasing around 6 kinds and cleaning and goats and ....life

....dont totally deprive yourself..diet soda, crystal light, sugar free candy..can all be worked in to help with the mental side of "loosing your goodies" and in to large amounts will give you the runs so you'll be more aware to keep it reasonable

lol
.... if you can get some whipped honey..it can turn anything into a treat and as mentioned before your body processes it slower. Swan's honey from Albion maine is a great source that i know of... i'm sure there are others too somewhere
hope some of those are helpful! and know, i'm right there with you in this...down to the 6 kids and goats even
