So you put it under your tongue? Is that to get it directly into the blood?
Also, you might want to consider taking it at night. See that way it'll help you sleep better, as opposed to make you tired during the day. At least that's the effect for me.
I only take 50mg, and as i said either for Depression kicking my butt for a time, or sometimes if I've had some pints that day. It seems to help avoid next day blues.
