For me Straterra lasts about 10-12 hours which is just about perfect. Unfortunately though for me the longer I take it the shorter that time slot becomes until I up the dosage again.
I've been taking it for about 18 months and it's down to just about 8 hours for me now and for those 8 it's still okay on effectiveness though I feel it could be a bit higher.
Basically when I up my dosage it works great for awhile then kinda starts winding down a bit.
It's commonly prescribed for ADHD, my doctor wanted to try non-stimulant based meds first because of my extensive history of substance abuse and also because of my diagnosis with anxiety and PTSD.
Anxiety is caused by Dopamine? I am not sure here, but would expect it to be bound to low Serotonine and high Adrenaline and Noradrenaline (aka. Norepinephrine).
Noradrenaline (aka. Norepinphrine) causes alertness and is associated with the "fight of flight response".
I have no idea why somebody would prescribe something for a person with 1. ADHD and 2. Anxiety issues.
But I assume the person may know better.
ADHD, to my knowledge, is mostly an issue of overactive pumps removing Dopamine from the synapse slit too quickly.
I used drinking Coffee, or Modafinil (which afaik also works on noradrenaline) as a substitute which tbh is pretty bad. I have the feeling that Amphetamines are better.
But I will have to see under exactly the same conditions. For example on Modafinil I could spend a day hyperactively doing random shit I shouldnt do. This might as well happen with Amphetamines, I will have to see that.
