Rebel2, I have heard that ADs can take up to six weeks to become fully effective. I've also heard that start-up effects like nausea and worsening anxiety can last for a couple of weeks but should diminish.
If you were feeling better mentally that soon, I would take that as a positive effect and maybe cut back your dosage for a couple of days since you have plans to go out?
Do you have IBS? I have IBS-D (predominantly diarrhea). I've heard the SSRIs are better for people who have IBS-C (predominantly constipation). Zoloft is supposed to be good for IBS-C.
But, really, if you were feeling that good that fast, I'd find a way to slowly build up. Most people are expected to feel worse with anxiety and mood before they feel better on an AD.
Lots of hugs to you! I'm rooting for you and all us of to find the treatment that will make us feel better!
