Overcoming MDMA and Meth cross-tolerance

[Zugzug]

Hi, so I have searched and not found the info I am looking for. I am a daily methamphetamine user for ~2 months. I use street meth, I live in a border state so it's pretty damn cheap. From my estimates it is between 30-50% purity and I typically use 100mg per day. I am estimating the purity because I had some very pure stuff from a visiting friend and I went from needing 30mg to get high on the good stuff to needing 100 overnight on the crap from the streets. I take great care not to increase my tolerance and use all supplements recommended. On the weekends I binge with my girlfriend typically using about 250mg over the course of 36 hours, she will use maybe 150 in that same time and she only uses on the weekends.

So the same friend also left me some MDMA. I used in the past, generally reaponsibly. I haven't used MDMA in about 4 years. I have a 4 day weekend coming up so my girlfriend and I booked and paid for a room and are going to roll. It will be her first time taking it. Then yesterday I thought to myself, does meth cause tolerance to MDMA and looked it up to find out it does. So now I'm worried.

Does anyone have any advice on how I can overcome the cross tolerance? Should I just take more MDMA? If so how much more, I was planning on the standard 1.5mg/kg with a booster of .5mg/kg an hour in. Should i do DXM the night before to potentiate? Or should I mix a little meth in with mine (30mg of the crap stuff so around 10-15mg) . I'd like to avoid mixing the two since my gf had never rolled and I want us to be on the same page and obviously I am aware of the nuerotoxic effects of mixing the two. I'm absolutely terrified of losing the magic and not getting to share the beautiful experience of her first time so I am hoping to get some solid advice. Also as I stated she has been using ~150mg the past 3 weekends with supplementation. I am assuming this will have no effect on her experience due to the short history of her use.

Here are some additional details
Substance: MDMA crystals ~80% purity no active adulturants found with separation testing kit.
RoA: Plugging
Environment: Motel room, just the two of us, set up with portable led light show, light up plushies, Vicks, sensation toys, massagers and some nice low tempo dubstep (think Distance or older Datsik)

I am not reducing dosage for plugging due to the 80% purity. Also obviously I have stopped the meth as of today so I will be 3 days clean. Lastly I apologise if this double posts, I tried to edit and think I accidentally deleted.

I'm just bumping this thread that sadly never got an answer because I'm curious whether people have anything to say about how long and how severe the cross-tolerance between METH and MDMA is.

When I was using METH at least a few times a week I felt nothing, nada, from MDMA even in high (200-250mg) doses. In the weeks since I've stopped using meth I still pretty felt nothing until maybe a month of zero stimulants when I began to feel a bit of a roll on a high dose of MDMA.

I'm curious about other people's views and experience on the medium to long-term effects of chronic METH use on the ability to roll.

this is interesting because normal amphetamine didn't seem to negatively affect mdma roll, if anything being on once daily amphetamine made the roll much stronger with less though i had low md tolerance back then.

the maddest mda roll with open eye haluciantions that were the best of all my whole life (think gnarls barkley inkblot rhino just running accross the room like cgi) were when i was daily ampetamine user, i wasn't using loads either, just a line for breakfast once a day

You're more than likely going to do a lot of jaw grinding towards the end. But typically mixing both has a good euphoria don't let the vibe go awry. Just be careful with your dosage and have fun.
