over 2 months ago, i developed loss of smell and taste and sensations in my internal organs(fullness or emptyness of stomach is gone). At the same time i noticed my vision started to act wierd, i already am aware that im nearsighted, but this is different. In low light, when i go to sleep in my bed, i notice the room was smokey, and though something was sizziling or on fire, then i realized that the seemingly visual smoke is the only one i can see, its like visual snow, but it wafts around objects like tables, black backgrounds(its more apparent). This all happened after i took benadryl, Dextromorphan, phenyleprine,acetomeniphen.
