First off I want to thank everyone for being so friendly and welcoming,I am a newby and i'ts a relief to not feel like an outcast.Anyway,I was having similar probs. on adder.,so doc. switched me to Concerta a few weeks ago 36mg./1 a day a.m. so far, FOR ME, it is much better.For one,it is controlled-release,so it did'nt hit me all at once and wear off by noon, or so. It says in the info it will help a.d.d. symp. (adult for me) up to 12 hrs,/day on one daily dose,I find it's more like 8-10hrs. FOR ME .No jitters,no extreme anything(including thirst)and no peaks and valleys all day long,and no mood or anxiety issues(as opposed to adder. FOR ME ). Adder. always hit ME like a ton of bricks and then kicked my legs out from under me when it was wearing off.PLEASE keep in mind that this is MY personal experience.I am not advocating Concerta and bashing Adder. to you or anyone, things can work differently, for different people(and almost always do,I have found). I present this as a possible OPTION, and nothing more. None of this may apply to you at ALL, I simply wrote this because real experiences from another A.D.D.,A.D.H.D etc......sufferer, is always better than speculation and ignorance,even though I am new here, I truly believe we should help each other as best we can.I think we've suffered enough.Good luck! and thanks.
