Your doctor can prescribe a different formulation–changing from extended-release capsules to regular-release tablets (I was on 25mg regular-release tablets that could be cut), or specifying a certain brand of capsules (@farm_mom found Teva had the most consistent size and number of beads within a capsule–helpful to those counting and throwing out beads to taper–see @sandij, or @doorman on how to do this). Or your doctor can write a prescription for a compounding pharmacy to make tapered doses for you (the extra cost may well be worth it because you can glide down in incremental amounts, rather than make rather large jagged drops).

Ask your doctor about a "Prozac bridge"--essentially, the Prozac cushions the effect of no Effexor and lets you "ride out" the withdrawal process.–https://natashatracy.com/treatment-issues/withdrawal/antidepressants-effexorpristiq-venlafaxinedesvenlafaxine/.
