I had been in withdrawal for around 20 hours or so. I took Subutex at about 6:30pm and then shot up heroin ten minutes later and then shot up an hour later and then another time 2 hours later. I did not feel pwd. The first time I shot up I felt immediate relief but did not feel normal at all. A bit jittery. Slight rls but definitely a big improvement. The other two times I shot up I felt basically no more relief which is def not normal. I guess my question is: is the reason I didn't feel anything from the last two shots because the Subutex blocked it? And does that mean that the Subutex is in my system now and therefore I can take more without waiting 24 or more hours after I did that last shot? and I don't have to worry about pwd? I ask because I haven't been very successful in switching to sub. It's like it's either not working or I get pwd. I think it's because my habit is bigger this time but I hear people getting immediate relief in like 30 min with bigger habits. Anyways I really want to make the switch and it's not working. So does anyone think I can take more sub without going into pwd even tho I used heroin at basically the same time as the sub? Or should I wait another 24 hours and try again...?
