Hi, so I am currently 28 days clean from cocaine and 19 days clean from alcohol 
however this week I have two social events involving going out for meals and other people will be drinking. While I am fine and strong about me not wanting to drink I am a little worried about what to say to people, as they knew I drank quite recently. I can just say Iām driving or have other commitments after but I donāt want to have to make excuses forever. I might add that one group are mummies from my daughters school, so Iām not very close to them and donāt want any judgement and the other person is a new friend who Iāve only met once before so again, donāt want to give any negative vibes or have her presume the worst. My close friends and family know the truth and I have alot of support. Thanks guys
Start with no thanks and end it there too. You donāt need to elaborate.
Sometimes I take breaks from drinking and I just say I want soda or water instead. Period. Iād never think poorly of someone who doesnāt drink, regardless of the reason.
+1 as ever to @CaptAZ. I find āno thank youā goes pretty far. I was also nervous about this, but people are usually cool with it.
For the few who arenāt, Iāll throw in a āBut I am pretty thirsty. Do you have some water?ā kind of like @anon62920945 said. Gives 'em something to do. 
Iāve gotten much more comfortable just saying Iām not drinking-and if theyre like yeah but you can have drinks: for the special occasion, just one etc Iāll follow up with āI just hate how I feel the next day, even one gets me hungover these daysā. I mean who canāt relate to a hangover.
Thereās a whole host of reasons you can use. Early start in the morning, driving, just getting over a cold, on medication you canāt mix with alcohol, you donāt drink very often, on a detox and taking a break.
Stop stressing about it, just be confident with your choice and reason and people couldnāt care less, if they do, they likely have their own problems.
That way youāre not really making an excuse and you wonāt feel uncomfortable ālyingā. I have about 120 days sober, and now I just say āI donāt drink anymoreā. I donāt really use the words sober or alcoholic when speaking to normal drinkers. However if they press the issue I will say that Iām really enjoying being sober and usually the use of that word subconsciously know not to press the issue.
Well said.
If you feel that you have to give an excuse, you can simply say that youāre making healthier choices in your life.
