Combinations - Ketamine whilst under the influence of MDMA / ecstasy

[Lettish]

Swim has a session coming up which will involve copious amounts of MDMA. Swim will be using ketamine later that evening/morning. Will Swim's ketamine trip be affected by the high doses of MDMA? In other words, will his ketamine trip be nicer on normal (lower) doses of MDMA?

When Swim keeps dosing MDMA, he can only explain it as getting more and more f**ked. If he is in this state (MDMA doses totalling 2000mg over time (don't ask)) and doses ketamine up to and beyond K-hole amounts, will it produce a different kind of trip to one built up on low to normal doses of MDMA (200-500mg)?
