theyre both awesome. doc is more sedating, easier on the mind, much less mindfuck, more recreational to a certain extent. im not saying lsd isnt recreational, but at times its so profound you just have to sit down.
i took doc every day of a music festival, up to 4mg each day and had an amazing time that i was in complete control of. i mixed it with shrooms, dmt, mxe, coke, bathsalts, and lsd. the only time it really got serious was when i dosed the lsd. immediately after i came down from the L peak i needed to tell my friends how much i loved them. lsd is some serious stuff, doc is much more forgiving, at least in my experience
