Singulair makes me feel high

Anyone else experience this? I’m 30F, just started singulair on top of my normal flovent. Seems to be helping my asthma but shit, it’s making me feel high. Like literally feels very similar to taking an edible, though perhaps less pleasant. I take it in the evening and it hits hard, but the next day I’m still decently foggy. I know about the mental health side effects, but I wasn’t expecting this. Anyone else experience something similar? I’ve only been on it 3 days and I’m hoping it gets better with time.
