weight issues

i guess the fact that knowing that i've lost weight will eventually make me put on more. when i found out that i was nearly approaching my target, i was really really happy. somehow, when i weighed myself today, i found out that i've put on 2 kilos.
probably it's all the merry making, the eating fiestas.. and the out of hand feasting on mcd's sundae (choco top). seriously, when i get back to penang, i must really double my workout. but then again, is it worth it???
