Those who reached your goal weight: did you have to go up to the maximum dose?

My sw 274 cw 249 gw 180. I've been on it for about 4 1/2 months. I stayed at 1.0 for a few months because I was dealing with a lot of nausea. I still seem to be losing about a pound a week which is great. I was wondering if those who reached their goal weight, did you have to go up to the max 2.4 dose to achieve this?
