Yes it will have some effect on the roll, however there is no need to up your dose. If you've been taking that kind of K-pin dose for a long time, the effect will probably be negligable.
However, it also probably means you're prone to anxiety/panic, and MDMA can bring those out in people who are normally fine... so be cautious. You're K-pins will help calm you down if this does happen, just take you're normal dose and wait.
