Coming off of lyrica (pregabalin) 25mg p.w, & increased cipralex to 20mg last friday. im having increased anxiety & suffering early waking every morning 5:20. why?

Short Term: You are stopping a medication that is sedating and has some immediate anxiety reducing effects (lyrica - pregabalin) and increasing the dose of a medication that has delayed effects on anxiety, that is not particularly sedating and that can have some short term activating effects (insomnia, jitteriness) (cipralex, Lexapro - escitalopram). For a week or two you can expect these effects.
