I've tried bothand alcar, and both of them had the opposite effect of what i was hoping for. I couldn't process thoughts, and they made me anxious. I had really high hopes for both of these, but apparently my body chemistry isn't cut out for these substances. Has anyone else had these types of issues with noots? I do take and sometimes with no problem, but they're more for getting into that relaxed state, and they work pretty well. I was really looking for a mental edge from the aniracetam and alcar, but like I said, they had me feeling confused and unable to think straight.
