So this is your chance! Youâre in recovery now and you have the opportunity to build the life youâve always wanted! 1  To get started, look in your heart and soul and find that thing that makes life worth living â and then build a long-term goal around it.  Once youâve got this, the rest is simply mechanics and sweat.
This will provide both fast-acting and sustainable energy to your body. Try to eat a snack within two hours of exercising, but wait a minimum of 15 minutes after exercising before you eat. Bring a snack along to the gym with you, so you can eat as soon as your workout is over.
Depending on how heavy a meal you eat, you should wait 30 minutes to two hours before exercising. The bigger the meal, the longer you will need to wait. If you just eat a light, high-carbohydrate snack like half a bagel or a few low-fat crackers, you should be good to go almost immediately.
