HELP I enjoy be have loud hiccups for that finishing 2 days??

I have tried sugar, holding my breath, drinking dampen backwards from a cup and a few others, NOTHING is working. Its really annoying cause they capture loud and I work with a great deal of people and own to talk on the phone. Any suggestions? The single thing that have been specified to get rid of hiccups and have worked everytime for me is stretching out your diaphragm. You basically lay down flat on your put money on and push down on on your diaphragm and hold your breath and stretch it out and down with your hand like you are pushing your tummy towards your foot. Hold your breath and then tolerate it out slowly as you push. May take few times, but should attain rid of them. What is happening is your diaphragm is spasming. You take rid of that by stretching it out and stopping that. Good luck. Hiccups stink.
Sip several times on white vinegar.
