How many mgs of tramadol do you take per day? 50...100....150....more than 200?
Only reason i ask is that you have an opioid tolerance and kratom isn't really that strong. So you may have to dose it in a larger quantity than someone who had zero opioid tolerance.
Welcome to Bluelight Shilo. 2 capsules is only 1 gram of kratom. Not real sure you are even going to feel that. I would start with 3 grams ( 6 capsules ) and see how you feel.
You can take it right now or before tramadol or after tramadol. Kratom is only a partial agonist at the MU receptor and a pretty weak one at that. Extracts ( tinctures ) are stronger but you just have capsules so there is no danger of OD or respiratory depression or anything that will harm you.
Keep us posted on if you feel anything from the 3 grams you take. With an opioid tolerance you may need a bit more.
