You'll be doing yourself a favor, if you draw a bigger lesson out of this whole experience. You're inclined to be impulsive, and prescribing for yourself is an approach that is not working for you.

Fess up to your doctor that you made changes on your own that didn't work out too well and that, now, you'll like to try being fully compliant with doctor's orders. Having him on board what you are doing can help with insurance reimbursement in the long run. If, after taking what he prescribes, you aren't happy, then contact the MD and tell him what's going on. You and he/she should make decisions together about any med change.

There are people who can act more unilaterally and have it come out okay. But you are not one of those people. You're flipping around chaotically, and your doc has no idea what the heck is going on. Ritalin is a highly controlled substance and the law frowns on self-medication with this type of drug. You'll end up putting your doctor and your pharmacist in the position of feeling that they can't trust you and that they risk trouble with the feds.

Work with your doctor. Speak up if you find something is not working out. Most doctors want honest feedback, so they can adjust your med to what works best for you.

When you earn the trust of a doctor, often he or she will be very accommodating to what you report as to what works and what doesn't. Doctors will even let you experiment to a degree. But that comes after you earn the trust. Change your approach, and you'll be much happier with the outcome. Nowadays, doctors are under much more pressure from the government to prevent patients from fooling around with their meds.
