What should I expect and how many tabs should I take?

Will it reduce the trip significantly or not?

yes, it will reduce the trip, and it's not even worth taking. The two antagonize each other. Why not go off of lexapro for 35 hours (citaloprams half life) then do it?

no it will not significantly effect the trip, i know this from PERSONAL EXPERIENCE.

i tripped twice with LSD while taking lexapro and felt no differnet

yes. they will antagonize each other, but as seeings as lexapro usually comes in 10mg tablets I recommend you take 2-4 hits.
