I haven't dropped acid in many, many years, but it sounds like you took about 100 mics. Double or triple that is much more intense - that used to be the normal dosage, which lasts a few hours longer, also.

You are right about not being able to sleep on it.

The visuals are as you describe - not as animated or imaginative as say, mescaline hallucinations.

I remember the physical feelings, sometimes "rubbery" sensations, usually happening in the beginning and fade about a third of the way into the trip. Better acid has less of this, and more of a "euphoria" sensation - with rushes brought on by music, or other stimuli. Toward the end, there is the famous "white light" sensations of enlightenment.
