This was my first I-Doser dose. It sounds like what you get if you stuck your head in a washing machine on the spin cycle. I definitely felt something, but not as successful as I had hoped. It gave me a headache, then I began to sweat. My cheeks got really warm and felt like they were swollen. I felt like a zombie or a vegetable, but at the same time in a dreamy state. There was mild euphoria, and I could tell my mind was trying to make things move, but just wasn't there or strong enough. It does work.
