My boyfriend recently passed away he was 37 there was butane gas found in him . He was found with a plastic bag over his head and a tube. I spent a lot of time in his room and when I I stayed over the night the day after i would feel extremely drowsy and no energy couldn't keep eyes open to watch a film. Kept having to have coffees. There was also a plastic type smell on his face mainly forehead and some pillows. I'm so confused I didn't know until recently his ex said he used to do gas years back and never kept it in house for that reason. Would I of felt that way because he was using gas? ? I'm trying to make sense of it all.
