I had a period of about a year where everytime i went pilling was fantastic. Textbook case.
Then some shit went on in my life and every time i tried to pill, it always turned into paranoia and anxiousness, very negative. ie: i broke up with my g/f, and we tried to relive the experiences we used to have and went pilling together but it was just plain nasty. We both got very vunerable and uncomfortable. Very hard to let go and enjoy ourselves. Too much on the brain is the way pills get destroyed.
Now it seems i can roll properly again (textbook symptoms hehe) without this, as i sorted out those issues in my life.
But this is what i reccomend for people who have bad experiences on GOOD drugs:
Find how to stop your head talking. To start rolling, you need to let go. Thats the hardest thing to do sometimes. Dancing would make me anxious and wouldnt let my body relax. Overstimulation is the problem. This happened to me once and i only started to roll once i locked myself in the toilet and stared at the wall for 5 minutes. The simplicity took over. Then A + B started to equal C and things started going well in my head.
I find that no people you are with can fix the problem its always something you have to conquer yourself. Find some space and some way to let go and clear your head. A joint may or may not help. It could relax you or it could make the issues more complex and hard to deal with in your head.
If the stimulus isnt working, then take a step back. If you arent enjoying the stimulation get away from it. Find your simplicity then go back, and the stimulation should flow nicely. I hope this makes sense.
