To help provide useful advice for people dealing with mental health problems in the effective altruism community I've written up my experience trying Wellbutrin / Bupropion to treat mild depression. It starts:
This isn't professional medical advice, it's just my experience and amateur knowledge. I'm an economist not a doctor.
Summary
- I wasn't sure whether I should try antidepressants because I was only mildly depressed, but I gave Bupropion XL a go.
- It was easy to get, cheap, and I think it enhanced my life a lot.
- Studies suggest this is a pretty common experience, and Bupropion is likely the best antidepressant for some groups of people to try first.
- So if you're ever depressed and live in or can visit the USA, or another country that prescribes it, maybe you should consider taking it too.
- Note that you should be willing to stop taking it quickly if the experiment indicates it's not helping you, or is causing worrying side effects.
- I note some kinds of people for whom it's probably not the best antidepressant to try first, and link to further research on the topic.
My experience in more detail
A lot of people suffer from depression or low mood and take antidepressants, or wonder whether they should take anti-depressants...

Was chatting with Gwern about this. An excerpt of their thoughts (published with permission):
I took bupropion from about February to November 2021.
After a pretty rough transition I found it to be a quite effective antidepressant, but it gave me very bad insomnia which I needed to take sleeping pills to overcome (this kind of sucked as it meant I had to be very careful to take all my meds at the right time of day, and couldn't increase the dose). I'm also quite confident that it made me more anxious.
That said, I would still definitely recommend it over SSRIs or mirtazapine, both of which have very common and serious side effects that I think are worse than bupropion's for most people.
I'm considering trying bupropion again when I move to the US in 2022, since there is a shorter-half-life version available there that is not available in the UK.
Thanks so much for writing this! I'm commenting so that more recent readers can see it. Wellbutrin/Bupropion can really be life-enhancing with very limited (to none) side effects.
I appreciate this!
Nice. I love ideas with the shape of "Consider trying this thing because the costs are low, even if you're not sure if it will help or pretty sure it won't."
Given confounders like this, it'd be great to see someone run a Gwern-style controlled trial on their Wellbutrin use. The value of information would probably be quite high.
It'd be sorta tricky to do given the on- and off-ramping effects of the drug, so perhaps should only be undertaken by someone with sufficient slack to accommodate.
