Slowly Eliminate Favorite Foods/Drinks
How hard can it be to forgo food and drink for a day? More than you know. For me, the first few days of Ramadan are spent in a somnolent stupor as I withdraw from caffeine. And an abrupt food/drink/nicotine withdrawal can take away from the spiritual benefit of fasting. Thus, try cutting back those things on which you are dependent for a week or two before you plan to fast. Start drinking decaf coffee, cut back on sweets, and cut down on cigarettes (if that's your vice).
