| Symptoms of withdrawal | Symptoms of withdrawal during the SSB withdrawal period (days 6-8) will be compared to symptoms of withdrawal during usual consumption period (days 1-3). Three measures are used to assess withdrawal symptoms: Griffiths' withdrawal scale, the relative reinforcing value of soda, and daily check in questions on well-being. | Days 1-3 and days 6-8 |
| Measure | Description | Time Frame |
|---|---|---|
| Change in diet | Changes in diet will be assessed by 24-hour dietary recalls and beverage recalls | Days 1-2, 6-8 |
| Change in impulsivity | Impulsivity will be assessed via the delayed discounting task |
| Measure | Description | Time Frame |
|---|---|---|
| Compliance with intervention to only drink water and unflavored milk during the SSB withdrawal phase | Using measure of salivary caffeine, beverage recalls, and 24-hour dietary recalls, we will assess compliance. | Days 6-8 |
