one summer night, i had to call an ambulance to get my friend who was seizing up / shaking / foaming at the mouth due to 4g shrooms (i took the exact same batch and I was fine).
This was his first shroom trip -- and I took 4g on my first trip too, and experienced ego death etc. but I look back on it as one of the most important moments of my life. That was the point where I took a good hard look at myself, stopped being unhappy with myself, and decided to do something with my life.
So I was hungry and wanted to get some Tim Horton's donuts while tripping (only a 5 minute walk from where I live + not much food in the fridge) -- except he couldn't walk in a straight line. I told him let's sit down on the grass behind where I live. I went to the washroom after 1 hour and then when I came back, I saw him starting to seize uo so I had to call 911. I grabbed his hand and everything, squeezed it, called his name repeatedly, etc. but nothing worked so I had to make the call. I had to keep my knee on his side in case he vomited before the paramedics came.
When they arrived, I pulled his wallet + ID out of his pocket and asked the paramedics to leave a note for him to call me in the morning so I could pick him up. They said they deal with these calls like once a month, and it's no big deal, my friend will be OK in the morning.
So the next day, he ended up calling my other buddy (who is totally anti-drug... and since this day we stopped being friends) to pick him up. The next day I threw a house party and when I saw him, he said 'When you grabbed my hand last night, I thought you were my spiritual guardian who was gonna guide and save me from the shroom trip"
