Bad reaction to mixing LSD with heroin. Has anyone ever experienced this?

[burn out]

So heroin and LSD used to be my favorite drug combination. I would usually take the LSD in the morning and then as the trip was wearing off I would do a large amount of heroin, put music on and sink into bliss. However the last time I attempted this combo, I felt so sick. It was like the LSD made me 100 times more sensitive to the opiate nausea and no amount of heroin would bring me any euphoria or good feelings, just dizziness and sickness. It was so bad in fact, that I am concerned about even taking LSD again because I am afraid that even taking the small amount of heroin I need to take during the trip to stay out of withdrawal will lead to nausea. Are there other opiate addicts on here who regularly trip and what have your experiences been on mixing these two substances? Thanks.
