Let's just say that I've done my research on this subject...
You do NOT want to roll two days in a row.
Assuming you aren't a troll, how do I even begin to convince you?
I have tried this on three occasions.
The first two were a clear warning - it is NOT worth it.
The second day resulted in 50% euphoria compared to the first night, maybe less.
Meanwhile, the negative after-effects were multiplied by at LEAST twice.
Consider this carefully.
Is it really worth rolling half as much when the comedown is TWICE as bad?
Don't just take it from me, there are plenty of other posts on BL illustrating the fallacy of rolling two days in a row. Even among the regular users who break all other rules, there seems to be an understanding that rolling two days in a row is NEVER worth it. It is the ONE rule agreed upon by the arrogant users...
Or you could just listen to your own instincts. If you pay attention, you will know the answer yourself. It is a MUCH better idea to smoke some bud or drink some beer. If you are feeling any sort of 'afterglow' it will do the trick. If you aren't, you need to pay attention to this warning.
The THIRD time I broke the rule didn't turn out so well.
Just take a look at my username...
Yes, there were other risk factors involved...
But rolling two weekends in a row and two DAYS in a row was enough to result in catastrophe the FIRST time. Need you tempt fate?
Aside from all this...
There is an abundance of research that proves that re-dosing causes the most damage. It is seen time and time again.
Typically multiple doses are given over a four day period.
Yes, the doses are normally large...
But the data is clear - repeated exposure is the MOST reliable way to cause damage to the serotonin nerves in your brain. This is no debate about this, anymore.
Even if you only do it 'this once', you will probably find it isn't worth it.
As far as supplements - I see no problem with anything other than 5-HTP.
It is associated with Serotonin Syndrome, something you do NOT want to experience. Pre and post loading is a bad idea. It would be wiser to simply eat a tryptophan-rich diet during the days leading up to your first roll. That means protein, by the way.
Post-loading with it has mixed reviews. I strongly recommend against post-loading between rolls.
Piracetam may be a good idea, IMO.
Without research to back me up, I believe it improves the brain's ability to rid itself of MDMA's toxic metabolites, which normally hang around for 3-5 days.
Taking it just prior to your MDMA dose may not be ideal. It takes Piracetam several hours to take effect - this is based upon extensive personal experience.
Not rolling two days in a row is the BEST advice I can give.
Apart from that, exercise is the next. It releases BDNF in the brain which has a direct and profound impact upon the plasticity of serotonin neurons.
If you insist on going forward with your plan, do some goddamn push-ups.
Watch your body temperature and drink electrolytes.
Good luck, and let us know if it was worth it!
