I have been taking Adderall for nearly 10 years. I have taken others like dextrostat, dextroamphetamine, and adderall xr. Now I am trying Vyvanse as Adderall over time has worked for shorter and shorter periods. It will only last about 4 hours, and I'm up to 55 mg 3 times a day. That may sound like a lot to most of you, but this is over a period of years, not to mention that I have a high tolerance to most things.

At any rate I am trying out Vyvanse, but it does not seem to work. I started out with 70mg and tried that for a few days -nothing. so I increased it to 140, and only noticed a marginal difference. I am nervous to try a higher dose b/c I have heard no mention of others at similar levels.

My questions are as follows:

Does anyone have a similar story? Is anyone at a higher dose than 140mg?

I did the trial just because I had the 30 day trial and I take a lot of dexedrine and I started at 210 mg per day, I took 2 70's in the morning and 1 70 at noon.

It was worthless, I take 45 mg of dexedrine 3 times a day so it wasn't quite what I am used to.

"I started at 210 mg per day, I took 2 70's in the morning and 1 70..." Thats for the Vyvanse, right?

"I started at 210 mg per day, I took 2 70's in the morning and 1 70..." Thats for the Vyvanse, right?Yeah he's talking about Vyvanse. I think he did the 30 day free trial of it but didn't care for it.

For yourself it's certainly worth doing the trial, but for effectiveness you will most likely need a similar/ higher dose. Is your doctor willing to do this? Or are you uneasy about taking the extra high dose? Keep us updated.

Just reread the OP and I would suggest if you hit 140mg of Vyvanse with no benefit, and the fact that you were on 55mg TID of Adderall, going up to 210mg makes sense if your doctor is ok with it. If you are worried about that high of a jump, you could go in 30 or 50mg increments until you notice benefit.

My former doctor retired and gave me pretty much free reign insofar as dosages go -which is likley true with everyone since no one can tell you what is or isn't the correct amount. Needless to say one must responsibly self-monitor, but I think this comes naturally as time goes on. I must say I think none of the doctors really know much about medication of this sort as most don't actually experience what we do, so in that regard I am certainly not 'worried'. I guess i have a higher than normal tolerance than most coupled with the fact that this is a new medicine makes me somewhat cautious as I do not wish to over medicate. But I am yet to recognize any sort of benefit from Vyvanse.

A 25 mg strength Vyvanse capsule is molecularly equivalent to 10 mg Dexedrine Spansules (both the aforementioned pharmaceuticals are about 7.425 mg dextroamphetamine).

Dexedrine dosages are 60-90 mg on average.

Very similiar story here. I had been at 120mg/day of adderall for about 4 or 5 years, when it just seemed to not last as long throughout the day. I began increasing my dosage, and of course, I began running out of meds before the 30th day of my monthly rx. This resulted in a week-long crash period that I couldnt tolerate anymore. So, I asked to switch to vyvanse. Was started at 70mg 1x per day. I find it does work, but seems to only last for 4 or 5 hours. I have started just taking a 2nd dose around noon, and that has helped me get thru the day. but of course, I will run out of meds early this way, and that is what I was trying to avoid. Planning on discussing with my Dr. after holidays.
