I started lexapro last nite and used 10 mg, and today I have completely felt like crap. Throat feels like it is swollen shut because I have cotton mouth from the lexapro. Also, I have had a slight headache all day, and just tired. Is this normal even after just taking it one time? The being tired could be from not getting enough sleep, but the other is from the lexapro. Does it stay like this? Should I go ahead and take my second dose tonite? I dread feeling like this again tomorrow.
