I Gained It Back...

I just checked my weight yesterday and the result is quite depressing. I gained back again those pounds I lost last week. Sigh! Why oh why is it so hard to stick to a diet? Does this mean I need to resort to safe effective diet pills this time? Anyway, I still owe myself another try. Perhaps I'll try a different diet and exercise routine to make sure I won't gain back again those pounds which I really worked hard to get rid of.
