Be patient with your body - weight loss isn't a straight line downwards, even if you stay firmly on the plan. You may get to your first mini-target by Easter (I certainly wish you that success) but you could also lose inches during that time and be happy with the change in size. The tape measure or the fit of your clothes is a better measure of how you are doing.

That's too bad about the caffeine withdrawal headache. Gradually cutting down is a fairly good idea - the headache only lasts a day or two.

Wishing you much success.
