It sounds like a contradiction - I thought serotonin was a happiness inducing chemical and cannot work out why you would want to inhibit it's reuptake (what ever that is). But I guess that's why I'm a project manager and not a doctor!

I find that chillis are a good happiness inductor. Although it only lasts for about 30minutes - this can be extended, if you have to go find some ice cream to cool down your mouth, and then a good cup of coffee to warm you up again!
