I Hate to add give my input on this one but I have seen this happen twice to my mate and the oly thing that helped was having more h till he felt better which normally would be in 5- 10 min.
But now firstly you need to take into consideration of how long you have been on subuxone and what dose.. as this will help determine the amount of H needed. And I would also advice to smoke it then never inject, as with the smoking you can gage it with every drag and with a shot it can be hot or cold. Too unpredictable
