I always had a hard time rationing my doses. Actually, I only do it with benzos, but it is not the same as opiates. If I have opiates, I will probably take all of them, or more than I had planned to take even though I am nodding my head and in my comfort zone. Even when the pandemic started I bought a 50ml bottle of ketamine of 50mg / ml, that shit has 2.5g of ketamine, I thought about rationing it and that it would last for months, but this was not like that, I ended up taking large doses and my nose was destroyed. Lately I'm going to the hospital to have my abstinence controlled, they leave me with serum for a while and they apply morphine, it's the only way to contain myself I guess ... here in Argentina there are no methadone clinics or something similar, I received methadone sometimes but the hospital in my city denied it to me after 2 months. So, I could say no, it is very difficult to ration my dose of anything, especially opiates, with marijuana something similar happens to me but it is not so compulsive.
It may seem funny to you, but the price of my DOC today is equivalent to 2 dollars. And I don't even have that, I'm sweating a lot and my anxiety is unbearable as is the pain.
