Last 10 pounds!

hello all! It's been a long 14 month journey and I have lost 55 pounds whilst living in Costa Rica. My stress level was nearly nil and food options were limited. I used MFP religiously and jogged 2-4 days per week. After 3 months in the U.S. I moved with my family to South Africa where I fell into a bit of trouble with my appetite control. The food is amazing here and I truthfully began snacking more, logging in less and slipped w bit. Not much, but a 2 kg weight gain (about 5 pounds) really upset me. I am climbing Mt Kilimanjaro in 9 1/2 weeks and want to lose another 10 pounds to be as fit as possible for this journey I have been training for past 14 months so... (Kindly spare unkind judgement) I asked a doctor for a one mo th script for Duromine to help me with the last bit. We agreed it would be one month only at the lowest dose of 15 mg and in just 2 days I feel more in control. Any experience in a similar situation would be helpful. I'm working out a great bit for training and my appetite has been out of control plus the food here in SA is amazing! Thanks in advance for any input and constructive criticism - cheers!
