Pardon me, that was what I was getting at with the 'dull' and the reverse. It applies to all your senses and taste is perhaps the most obvious of those. You could try three days then one day off. That usually makes things taste good. But to be honest I'm not sure that would be the counter-regulation of dopaminargic receptors. It's probably just being hungry after a few days of stimulant based appetite suppression.

To expect to experience significant withdrawal effects after one month you would need to be using it most days. Within-week cycling slows that down.
