Yeh man, for some reason my throat gets all tight n shit n the only way to swallow food is by taking it down with water. But hey, great way to drop some weight 
Opiates also make it VERY DIFFICULT to swallow. Like, very very hard to the point where I feel I might choke. I have this problem A LOT. On OPANA in particular its worst, oxy I dont really get it. Heroin sometimes I do too. Suboxone is actually the one opi that doesn't make swallowing hard.
