I really don't want to harsh your buzz because I'm really glad all of that happened to you, but antidepressants typically take 2, 4, even 8 weeks to work. Within a week is very unlikely. The reason I'm saying this is that there also could be serious side effects within that timeframe and, even if you're feeling better now, you need to be hyperaware of them because they include things like suicidal thoughts. Antidepressants can sometimes do the opposite of what is intended. The brain is complicated and it often takes more than one trial before you find the one that works for you. I went through at least 4 different antidepressants until I found one that worked- although I'm type II bipolar, making it more complicated, but my wife, who is not, had the same issues.

Like I said, I'm really happy for you that you got sleep and feel more energetic, but please, please, please pay attention to what your body and mind are telling you more than usual over the next couple of months.
