do you take it of a morning or night?

DH takes his of a night, and he is underweight. Has been on it for over a year now, and no effects on weight.
the dr said for him to take it of a night because it can make you sleepy..... hope that may help. Maybe switch the time of day you take it, or ask for something new altogether, but it's hard to find something that works for you, and has no effects....
