Do I have Serotonin Syndrome?

It's a little unlikely, but regardless I feel I could use another opinion on the matter. About a year back, I'd heard of 5-HTP and after reading up on it, decided to try it, albeit for the admittedly childish intention of having more vivid dreams. In the end, I found a better use for it; it alleviated my anxiety and made my less than perfect weekdays much sunnier. After I finished the bottle some time later, I felt anxious about the idea of potentially becoming dependant on the little tablets, but was surprised to find that this was not the case, and retained my happy disposition. At any rate, a few weeks back, I felt the dismal presence of self-doubt and gloominess creeping up again on my otherwise optimistic mind-set, and last week opted to try taking 5-HTP again. So i've been taking one 100mg capsule on and off before bed for about a week and a half I'm guessing. Last night, I don't believe I took a capsule before sleeping, but nevertheless awoke feeling feverish. No shaking, (except for yesterday after a cup of tea, but this quickly subsided), no sweating, and I do feel a mild soreness, but this is likely due to my running around lately. I don't take any sort of anti-depressant or MAOI's so far as I know. Once again, my imagination is probably getting the best of me, but if there is even the chance that this could be the case, I will discontinue my use immediately. Oh, and I smoke a little pot here and there, in case that may be a factor. Put my mind at ease, would you?
