Can I take the self-employed health insurance deduction on Schedule C if I pay premiums for a retiree health plan provided by my previous employer?

I know that you are not allowed to take the deduction if "you or your spouse could participate (even if you declined coverage) in an employer's health plan at any time during a given month."  But since I'm now retired from this company (I do consulting now} is it still considered that I have coverage through an employer's health plan?
