Adjusting meds is perfectly normal. Everyone has a different amount that works for them - don't worry if your MD doesn't!
Now if you are concerned and wish to keep the level of meds down and still keep the effect the longest - ask to be able to try med holidays. Then you just take one week cold turkey for around every 2 months on. It works wonders for me with dexedrine - I've been on 20mg daily for over a year now. Many find it keeps the meds from leveling or dropping in intensity.
Hey guys! Just needed a little advise and I knew you all would be able to help. I went to the doc today for my monthly check up. Aside from having to pay for the last I appointment that I forgot to go to OOOPS! it went pretty good. The only concern I have is that she uped my dosage to 64mg of concerta! I am a little afraid of taking this high dosage. The reason why she upped it was because the drug had began to loose it's effects that I benifited from when I started taking it. She said that this only happens when you are not on the correct dosage. Is there anyone else on there on this high of a dose? Damn I must be pretty bad if I need this much. I hate it when my wife is right!@!@!@!@!

I am off of work for a couple weeks at the end of May, maybe I will give it a try then. I am not so much concerned with how much meds I take. I just have never heard of a dose that high.
