If you're going to try tube feeding I would suggest taking it slow. At first, the tube feels weird and if you take it too fast you might hit the back of your throat without the tube angling down making you feel like your going to throw it up. I used a cup of water to swallow it down like some spaghetti. soft tubes are the best if you can tolerate it and not allergic latex tubes could work if not vinyl tubing can also work.
Two people are preferred for this method, but if not just attach a funnel to the other end and begin to fill yourself with a liquid fastener of choice (I.E.: Boost VHC, heavy whipping cream, and others). The only thing you would have to watch out for is how much you're putting into yourself as since you can't taste it you'll more or less have to really feel when your belly is at its max and if you want to go beyond the standard limits of your stomach.
