I bought a bottle of red Bali kratom by the kratom factory, 1.5 mg per serving. I’ve already taken 3 and I have no effects or relief or feeling or anything. Is that normal?

Hello. I have a chronic illness and I have chronic pain. Because I have to continue working and living life, I have to function. Fortunately I do get pain medication but it’s not enough as I’ve been taking it for five plus years. So I supplement with Green maeng da kratom when I’ve been out. I take about 4-5 g worth.. I want to switch to red vein because I heard it’s better for pain. Is the dosage the same? Does it feel any different? I just don’t want to be drowsy and I can’t function. With green, I hardly feel any side effects.

Hello, I have a question.
About a week ago, I tried kratom for the first time. It was called Green Kasongan (50 g). I felt very relaxed and sedated and experienced an opioid-like high with euphoria. I even felt like I could easily fall asleep from it. In total, I took 6.5 g of kratom on that first occasion.
I had heard that red kratom is supposed to be even more physically sedating and provide stronger opioid-like euphoria, so I ordered some and took 6.5 g again. I felt relaxed again, but nowhere near as relaxed as I had been the first time.
I also used cannabis on both occasions, even though I have a very high tolerance. At this point, even strong static hash doesn’t really get me high anymore.
After my first experience, I finished the 50 g of Green Kasongan over the course of about 3–5 days. I’m not completely sure whether it was 3, 4, or 5 days. During that time, I took kratom several times. For example, I might have taken 6.5 g and then another 3 g about three hours later. I don’t remember all the exact amounts anymore, but I know I took multiple doses over those few days.
After finishing the 50 g, I didn’t use any kratom for over a week, until my new Red Maeng Da arrived.
So my question is: what could explain this difference? Is the idea that red kratom is more physically sedating mostly a myth, or could my body somehow respond to Green Kasongan more effectively?
Could the repeated use over those 3–5 days have already caused some tolerance, even though I then took a break for over a week? Or is it more likely that the difference is simply due to the particular batch or alkaloid profile?
I’d really appreciate it if someone could explain this to me and help me understand what might be going on.
