I totally get it, back in 2011 when living in OC California I kicked iv heroin habit with 20, 10 mg methadone pills doing a rather quick titration and with the help of smoking a bowl of tina 3x a day, smoking tina always had this calming adverse effect on me, I could even smoke it right before bed and I would fall asleep just fine...but snorting that crap..ugh I'd be feeling awful with tachycardia and never sleeping. Weird shit.
Off topic I've been on Zubsolv about 8 mg once a day in the morning for 14 months now and I got a hold of some good Boy last night and I was able to feel the full effects of a shot of dope this morning exactly 24 hours after I last dosed 8mg Zubsolv. I have heard and read so many different situations of people having to wait at the least 2 to 5 days after a Bupe dose before feeling any effects of a full agonist Opioid, I guess it's very subjective due to difference of body chemistry/strength and dose of full agonist.
