I didn't know where to start with Idoser when i got it, so I got opium.
It was kinda neat really, it was a good beginner dose for me, but i don't do Idoser much so I really don't know.
I finished the dose, and it felt pretty good, I was in sort of a haze, I felt really relaxed, Calm, Happy and a tiredness came over me, And it seemed like somewhat of time dilation. The effects lasted a good 45 minutes (I kept tract but it felt like 2 hours)for me.
I have done the opium dose a few times and felt the same effects every time.
Awesome dose in my opinion and a good starter dose I think
