Flugels were lab tested as 240 so if you boshed 2 very likely you'll be tripping. As rightly stated due to conversion in body to MDA at high doses.

Careful you'll be taking the BL Cookie Monster title from Small Town ?
Alcohol fine as a diuretic aid couple drinks prior but it's really a waste of good MD to get the hammer down during, as the two don't synergise well. I simply can't touch alcohol until at least + 3 and never have wanted to when I'm on a good un. Maybe it's personal and the way I view the experience - want it as pure as possible. I can go get pissed whenever but I can only do MD every so often. Firm believer in doing the drug you want and getting the most from it mentally and not simply using to get smashed.
Warning as per a post a long way back excess alcohol intake is a sure fire way to increase potential toxicity and increased workload of the internal organs during the roll, lowers inhibition reduces effect so likely that you take more than you would without. Also dramatically increases the comedown, I find, and nothing worse than a hangover from alcohol it ruins any chance of an nice afterglow.
Best you can do is to drink isotonic before and after dropping and next day. They replace and restore bodies natural balance. Swear by lucozade both before during and after it really does work.
Coke is a real waste. Both of the coke and the MD. I would need to double the MD intake even after consuming a line two hours prior. Also increases risks dramatically.
Really the only roll mates I've found to be worthwhile and add LSD, 2 CB, weed, nitrous. Probably a lot more but those are the ones I've tried successfully. For example 3 FPM appears for me to reduce all of the empathetic quailty and turn the roll very stim orientated. Speed used to be a regular combo but I found it very dangerous as it did end up with having to take more MD to balance the speed. I don't include Benzo because they are purely for the point at which sleep is essential. If you suffer aniexty on the come up then take less or perhaps consider MD is not your DOC.
As always everyone is different so ones mans meat maybe another's poison.
