I've been experiencing a lot of benefits from the Concerta, but am still unhappy with the inconsistency-- Taking 36 in morning and another 18 in afternoon, to try to alleviate the ups and downs and while more days are good than bad, there are still some days where it just feels like a roller coaster ride! I'm reluctanct to switch to something else because I don't want to lose the benefits I AM experiencing, and I've heard it may take awhile for other meds like Adderall to take effect. (My doctor has indicated that Adderall would be the next step.) Would like to hear from anyone who has made the switch from Concerta to Adderall- Did it seem to last longer for you, or did the effect seem more stabilized or even? What about the Adderall XR--anyone with any experience there? How much Adderall effectively replaced the Concerta for you? I know everyone is different and just because something works for someone doesn't mean it will apply to me. But I'd like to hear some success stories in case we do decide to go that route. Thanks in advance!!
