I think my drink was spiked..

I’m a guy I was drinking at a pub…a guy collapsed and had a seizure in the outside of the pub I then got talking to 2 guys which were close by and I said surely he’s on drugs they said nah that’s just drink….ambulance took the guy away I got talking to the 2 guys just chatting as you do…that pub got a bit empty so we all suggested to go to a bar down the road they kept talking about drugs etc when we got to the new bar they had security and ID scanners and I qued up after a few minutes they walked off and said nothing to me…after 10-15 mins of being inside I was running up and down and began to gag I went downstairs got a drink and apparently started to touch people allegedly put my arm around a woman and even groped another womans bum I got kicked out of the bar and then was walking up and down the street screaming I actually got arrested – I’ve never been like this on drink and I’m literally stressed to high heaven what on god’s earth type of drug make someone act like this? I had chest pains for 8 days after and have had a slight blur on my left eye since I’m literally having the worst time of my life over this
