I just wanna throw something out there. Years ago I was at a Stones concert & dropped acid for the first time. I expected...you know...my money's worth. I did experience a serious wave of nausea, did puke. After that all I felt was "flat". Everything seemed toned down...colors not as bright as I was used to, music lacked the gives me chills ecstasy I was accustomed to. Very disappointing. I didn't know what to make of it. Figured I'd been burned.
A couple of years passed and I had the opportunity to do acid again. Figured, This time it'll happen. Nope. Same result. Felt the nausea wave, then...flat. Mediocre. Grey concrete.
About a year later I sought psychiatric care for a severe depression. I ended up being diagnosed with bipolar disorder. Decades later and I'm still in treatment for BD. Recently I spoke with my psychiatrist about my experiences with LSD. Her take was that the acid had actually brought me down to "normal." My usual state was hypomanic-manic. She reminded me of all the research that's being done now with hallucinogenics and certain mental illnesses, especially depression and mood disorders.
I'm definitely not saying that you have a mental illness. I'm just adding my experience to this thread because, for some people, a lack of the expected response to LSD might be indicative of some type of psychiatric disorder.
