Hard habit to break, but if you are determined, you can do it. Here is my advice, but someone else may have a better idea.

Use a soft target like a bag target or a big chunk of soft foam (to avoid damaging your arrows). Stand back just far enough that the arrow will clear your bow good--so close that you can't miss. Close your eyes and concentrate on reaching your anchor. MAKE yourself anchor before you release. You stand close so you don't have to think about accuracy, missing, loosing arrows, etc. This is also great practice for form in general. Draw slowly and deliberately, anchor, hold, release, and finish with an exaggerated follow through. It may take some work, but you can do it!
