My mother has been having me take this because we haven't been able to afford getting my Lexapro prescription until fairly recently. This has been going on for five months, since October. I'm supposed to be taking 5mg Lexapro each day, but this Wellbutrin is a 200mg dose, that she's been having me take every night since. Are there any bad side effects to taking this med with such a massive gap from its expiration date?
