12 pounds is GREAT!!!!!! Just keep on going....in these next few weeks do not expect much as your body needs to do some fence mending...and these next several weeks usually do not show much in the scale dept.
You may want to avoid that scale for 2-3 weeks...and go by how clothes fit instead!
Oh yeah...be sure you have taken measurements....write me down...you WILL lose inches these next 2-3 weeks...and maybe not pounds. THIS IS NORMAL, so expect it!
BEST wishes and COngrats on the 12 lbs!
