Should I Consider Seeing A New Psychiatrist If My Current One Seems Unfamiliar With ADHD Medications?

I have been seeing a psychiatrist biweekly for ADHD/OCD since Nov 16. I was on Stattera for 7 weeks till we switched to 5mg adderall in the mornings. I was a little confused she didn t want to see me back in 1 week with such a low dose. So after 1 week and not feeling any change I bumped up to 10 mg in the morning for then next week. When I saw her, she was ok with me going up to 10 in the mornings but when i told her I felt no significant changes, her response was Well then I don t know what to tell you . Eventually I got her to agree on 10 mg twice a day 6am and noon. even though I told her I can feel the medication wearing off 3 to 4 hours after ingestion. I asked her about dexedrine because I read that it s better for people who have ADHD and OCD and she didn t know what I was talking about. come to find out that Vyvanse is the new similar dexedrine with the L-amphetamine. I guess my question is, should I see a new psychiatrist? I feel like she gave up after only trying 2 adhd medications and I ve been doing a lot of research and feel like I know more about this stuff than her. When I mentioned the 3 times a day (which I seriously feel like I need because I have long days) she scuffed at it. Didn t even increase my mornings to 15 or 20 after I have already tried 10. I m trying to be patient but I , not even sure SHE is being patient. And lastly, bi-weekly appointments??? I already know if the first 3 to 4 days if what I m prescribed is working or not. Non-stim is one thing, that takes a while, but adderall?? I feel like not being on the correct dose is what s making me want more where if I was on the right dose at the right times, it would just all fall into place. 20 mg in the am, 15 mg in the late morning and maybe 5mg in the afternoon to minimize the crash. Sorry for the book. I just need advice on whether or not my psych knows what she s doing.
