lol , this perfectly captures the problem with guns . They are subversive in and of themselves . If the government banned a cell phone , no one would bat an eye and they didn ' t the GN 7 was banned . But a gun ? Then we ' re going to literally start killing people until you agree we can keep our guns . That ' s how much we love freedom . We ' re going to murder American soldiers until we get our way . Democracy means respecting that sometimes you don ' t get your way . <| sep |> This is for . Matilda . I ' m not crying . You ' re crying . <| sep |> Well they were always there , you just had to enable them with config tweaks . <| sep |> I don ' t think anyone can give you a concrete answer . However , I have read stories before where a person ' s response to a chemical just changed permanently over time . It ' s often called losing the magic . It appears that some people ' s bodies just adjust permanently to a chemical . It may happen quickly . It may take a while to happen . Or it may be affected be frequency of use . I have no scientific basis for that . I ' m just going off of what I ' ve read . In your case , it seems like your biochemistry just doesn ' t work well with aPHP or NEH . That may extend to all stimulants , or it may not . I believe these two are NDRI type stimulants , so it may be that you ' re more sensitive to NDRIs .
