Need to maintain my weight after 95lb loss

Hi everyone. I have over the last 10 months lost 95lbs. For the last 4 weeks I have been adding calories to my diet. I am up from 1000 cal to 1350 cal and still losing. I have added every week and in the last month lost 7lbs. I do not eat white flour or refined sugar or processed foods. Any hints has anyone been through this before? I exercise about one hour per day... 6 days a week it is 20 min cardio, 20 min strength training, and 10 min yoga and one day per week it is 60 min yoga. The calculator on this site says that I should be eating 2000 cal per day but the just seems so high. I am 5 feet 5 inches and 120 lbs. Any help that you guys can offer would be great. Also what are the fat and fiber amounts that anyone who commsumes around the calories as me are eating (I eat about 22g fat and 40g fiber is this ok?). Thanks in advance. I am feeling really frustrated with the process of entering maintenance. I never expected to lose so much (in fact my first goal was 165lbs) I just thought that I would stop losing and my body would stabalize so I am really feeling a bit like a fish out of water here.
