Generally its not that bad and ill cry if i hear a good song that brings me back, or just good memories will make me tear up.. But after my heavy usage this past weekend (little over a gram consumed within 2 days) i literally would cry over such little things, or see something slightly motivational or sad on tv i would just start balling. Im normally not a crier at all, pretty manly and off putting actually haha. Is this an obvious sign of low serotonin?.. Im good now, being a week later.
