Methylone is apparently very heavy on the dopamine side, deceptively so. But serotonin is certainly involved. How much it would matter to MDAI use is something no one here can predict for you.
However you should be very careful about using MDAI after such chronic monoamine depletion even if it is mainly dopamine issues, whatever side-effects like mood problems you might already have could swing into full effect if you keep pushing this.
You will find out yourself how you react to MDAI so I don't see what use it is to ask us. Just reconsider your intake of euphoriants / stimulants because a huge tolerance is a bad sign and it ought to urge you not to continue this way.
(Just for the record methylone discussion is now primarily for the OD forum while MDAI remains here, I can see how that may be confusing, in any case this thread is allowed here so don't worry. Just be aware.)
