They started to work after 3 weeks. I'm still taking them but overall, even if I'm after the first enthusiastic wave of energy, my capacity for reading is much higher than before. For context I started reading one book at the beginning of the year and I couldn't finish it before I started my therapy and after it (I started this March) I finished 3 books in 2 weeks. Currently I'm capable of reading around 4 books a month. I'm mostly reading academic philosophy and work full time while studying on university so it's a huge improvement for me. I guess the effect can differ but I believe it's worth a shot for everyone having similar problems.
not got anything against SSRIs or self-medication but given their low success rate & the withdrawal symptoms they can create, this isn't necessarily something I'd recommend
