i am sick and taking med. baby movement getting lesser and not as active as b4

Thank you all for your reply.... I didnt feel much movement ytd (except the hiccup), as in no 10 movements in 1 hour. The movement slowly decreased the day when i started to take med. Usually she is active after my meal, or 8pm onwards. And i also tried to drink some sweet and cold drink, sweet snacks, it also doesnt work. I never took my med for the whole day ytd. Then, i finally feel the movement getting more ard 12am... i think it could be the med make baby drowsy, despite the med is non-drowsy. Cos i also feel lethargy when having med.
