Dieting

 I started drinking weight loss shakes 3 days ago now. Yesterday was hell though, my stomache was making all kinds of noises and I felt like I was starving!! I ended up overeating at dinner and feel incredibly guilty. I was wondering if anyone had any suggestions to curb the appetite? I am eating the snacks in between like they reccommend, but I really feel the need to eat- this makes me feel guilty too!! Please can anyone help?

What sort of snacks are you eating in between the shakes? Sometimes this can make a difference, if you're still having hunger pangs.  I've found- and this is just for me, personally- that snacks high in fiber or water content seem to stick with me longer, so to speak. Drinking a lot of water helps, to.
I.. don't know if that's helpful for you or not, I'm sorry. :(
What kind of weight loss shakes are you drinking?

 I have been eating chobanni 0% greek yogurt. I am drinking Slimfast shakes, and yeah today I am trying to drink more water... I still feel hungry, but not as bad. Maybe I  need time to adjust to not eating so much. I seem to become discouraged easily with weight loss, but I really need to lose the weight, my joints click and I can't do some simple things that I used to, and I feel awful.

That could be it, to. It takes a bit to get used to it, i know. just keep it up, and give it a little time. :)
Yeah, i know, I have the same problem. I've tried a lot of things, and suffered a lot of failures (I gained weight on jenny craig, following their meal plan. ..yeah.) my knees are messed up, and I need to take some of the pressure off of them, so..
Good luck honey, and I hope your body adjusts to the change in diet soon. :)
