and congratulations on completing (in a day and a half) a clean Phase 1!
You are so smart to start planning ahead for your weekend. If we keep giving ourselves "time off" we never make it to our goals so planning your fun times in ways that work with your eating plan will really help you be successful. Phase 2 is all about figuring out how to make this lifestyle work for you and fit into your life.
Rum and diet coke should work but can you stick to just one? I've always found the issue with alcohol isn't what the first drink is as much as how many more drinks I have and how bad my food choices get after
I usually drink wine but order a glass of wine and a glass of seltzer. I like having something to sip and the seltzer helps me limit the wine, if that makes sense. Make sure there are SBD safe nibbles around all weekend so you don't find yourself straying to the chips with your drink.
How To Make This Work in Real Life might help too. Come back Monday and let us know how it went!
