Wellbutrin worked wonders for me. Works immediately, similar to amphetamines and is easy to obtain legitimately.
Depends on the country. In Europe, it's not so easy. In the UK, the last I checked, it was contraindicated for long-term use, meaning it could be used for smoking cessation but not for long-term ADHD treatment.
> similar to amphetamines
Wellbutrin has a very different mechanism of action, and a different effectiveness profile. I wouldn't say it's "similar to amphetamines" in any clinical sense.
It is not a typical treatment, but a psychiatrist in the UK does have the discretion to prescribe Bupropion off-label.
In my own n=1 experience, as a fourth option, only after unsatisfactory trials of more traditional stimulants and Atomoxetine.
For me it was like rediscovering caffeine for the first time, which lasted about six months altogether. Then the positive effects waned and it became a self-inflicted case of acid reflux.
Would never describe it as being similar to amphetamines. The most praise I can give it is as "an antidepressant that kinda sorta works."
