You deserve much respect for making this big step of being honest and asking for advice. For your immediate question - should you put your sobriety on hold? - I say no, for this reason: The odds of you truly getting out of the business in the next 90 days are a lot less if you're drinking than if you're not.
I'm not judging saying you should or shouldn't get out of the business. I'm going with your stated goal which is to get out.
So.....I would explore what lizw said about saying that you're on medication that requires that you don't drink for now. Probably would work best if you told them something specific, as in either the medication itself or the reason for taking it, but you'd have to be careful not to make it some medical condition that would make them less likely to do business with you. If you don't tell them something then they will think the worst themselves.
Best of luck, and please continue to post if for no other reason than it's good to have an outlet for your thoughts and it's hard enough for alcoholics to get that outlet without being in the escort business too.
You'll make it through this.
