Hi there- I was just like you! I would hallucinate and go into the whole paranoia thing when I tried pot-lol- Never took acid when my friends did,,,, I went thru a 5 day ketamine infusion (non stop) and I was fine! My hallucinations were good ones and I was like a happy drunk. I did have to have a full psych workup because they have to make sure your not psychotic- hearing voices etc. I hope that helps you. Feel free to email me if you have anymore questions. Good luck!
Remember though everyone reacts differently to these drugs

PS -they should give you some type of relaxer like versid or ativan to keep the hallucinations at a minimum
