So I just got a perscription of dexedrine

(which is quite sufficiently awesome) and I was wondering if all y'all mothers out there knew of any possible contradictions/interactions with any of the nootropics I am taking, or was taking, I've decided not to combine them all until I am reasonably confident it's not going to kill me. Just up until I began using dexedrine, which was this morning, I was taking, daily:
-Huperzine A 50mcg
-Pyritinol 200mg
-Centrophenoxine 250mg
-Idebenone 45mg
-Vinpocetine 20mg
-Phosphatidylserine 100mg
-Piracetam 3200 mg
According to my doc, I should avoid the following types of medications:alpha blockers, SSRIs, beta blockers, lithium, strong sedatives and veratrum drugs. Now I spent a couple hours on google trying to figure out if the nootropics I mentioned above fell into any of these classes of drugs, and Im fairly certain Im good to go. However I figured you wonderfully brilliant people might know something I dont, and if you suspect that I might be putting myself in danger, I'd appreciate the heads up. Good karma to you all.
