To the residue there was added a 1.0 M solution of HCl in anhydrous Et2O until the mixture was neutral as determined by external damp pH paper. A very subtle onset characterized most notably as a mild stomach ache that lasted a short while. There was a sort of vague unreal feeling at an hour, but my thought pattern seemed to be quite clear. In another hour I noticed that higher pitches of the music on the radio were being muffled and the tones seemed to be shifting to lower frequency. I phoned a friend, and first the dial tone, and then her voice sounded wrong.
Television seems amusing, but perhaps it really was amusing.
Soup tasted fine, and there was no appetite suppression. No GI problems, no next-day negatives. My thoughts became quite cloudy, increasingly so for several hours. And somehow slower than usual. Reading didn't seem to connect, and I had to turn the radio off as it was lousy.
