150ug or 300ug LSD Alone for the first time

So I’ve tripped about 15 times on LSD, highest dose being 500-600ug (bad trip). However, I’ve never done it alone, I’ve always tripped with people and every time I do, I always wish I could trip alone. Finally I have the opportunity tomorrow and now I’m a bit lost. I have 2 150ug tabs and idk if I should take both and chill or just take one. Also don’t know if I should do it during the day or at night and don’t really know exactly what I’d do. For anyone who has tripped alone, can you tell me what it was like and things you’d recommend? Thank you!
