best to get back to the doc if anything just to get reassurance and some comfort!

getting sent out into the world on a new drug can be a mind warp especially if you have never had anything like it before.

I don't know if you have had anything like it before my guess is no? and add medication comprises a bunch of powerful drugs

many people say drugs take a while to work and this is a deception...in the sense that yes it does take time for the body chemistry to incorporate and adapt and integrate what is introduced but a chemical will have immediate effects anyway.

...so it's affecting you but not necessarily working yet.

I was an amphetamine user for many years and moved onto prescription dexamphetamine so I was familiar with the effects. ( don't recommend that either)

...I'm no doc so I reckon just keep in touch with your doc especially in the beginning ...they won't be surprised it's a tricky time
