Is going back home on LSD a good idea?

You don't seem to get it. With LSD, especially with high doses, the effects will be different from person to person.

I could tell you that for me, personally, ~250ug dose was enough to have me tripping pretty damn hard for ~8hrs and then the effects started to gradually fade, but I was definitely a bit high for another 8hrs atleast after that.

But more than likely, that won't apply to you. Might be that you trip hard for a few hours and then the effects start to fade and you will feel comfortable talking to your father, but it could as well be that you will trip hard for the whole 12 hours before the effects start to fade.

My point is, no-one here can say how long and how hard you will trip with that kind of a dosage.
