Hi Bud, I've been using trazodone along with effexor for the last six months and have had the same side affects, I found that any caffeine(coffee or tea or coke)with in a few hours of taking trazodone would make me sick,I even vomited in my sleep once!That was very scarey,I thought I was going to choke to death but since I watched the caffeine I've been Ok. About the dizziness,I get that to but I fall asleep so fast it does'nt bother me...Well thats it for me.It's nice to know that these side effects are real and not just in my head...Remember Think Positive... ;)
