It took me a week and a half at most to feel better when I was taking it every night at around the same time.
6 weeks is way longer than needed to feel the effects of a new medication. It should take about 2 weeks
Every time I’ve taken it, I’ve started feeling better within a couple days. (That’s how meds in general are for me, even ones that “take time” to build up in your body.)
Only took me a couple weeks
