We decided to participate in Dry January and added on a Vegetarian (not Vegan) only diet for the start of the year. Another idea we discussed was also cutting out coffee, but two changes were more than enough. We did, however, try to cut the caffeine down to one cup a day and no sooner than 1.5 hours after waking up. But like I said earlier, crash changes are not sustainable or successful. So we planned some approaches around how to stick to and get the most out of these experiments.
