Combinations - Quick question: Modafinil and Vinpocetine

[Mish]

Hey,

I just joined 1 minute ago so I will introduce myself at some point soon, but for now I just have to ask;

swim has just taken 200mg Modafinil for the first time (in the form of Modalert from SunPharma) is it okay to mix this with 10mg of vinpocetine?
Also,are there dangerous effects if swim mixes Modafinil with -

Gingko Biloba
Gotu Kola
5-HTP
Piracetam
Pyritinol
Huperzine A

Swim doesn't want to harm his brain first time trying Nootropics..

thanks
