EFFEXOR 37.5 XR - new user.....help?

Hey Everyone! I just started effexor XR 37.5 about 5 days ago and man oh man I feel like I am in slow motion, no appetite, stomach issues etc. Can someone please give me some inspiration itll get better? Please? Im really struggling - the entire past weekend all I did was veg thats not me. Im so detached emotionally physically like Im not in my body. Does this get better? Ive been on lexapro, trintellix, walbutrin, prozac, and number of others Now we are trying this. I dunno if this is normal or what. I even had the genetic testing to see what rx are good and what are not and theres only 5, Effexor being one of them. Found out prozac is in the red I should have never been put on that. The others are yellow meaning they may help but depends on dosing may not be the normal amount, more or less,. Sh=o we are sticking with the green list which like I said is only 5 drugs. I tried going off meds for about 6 weeks and I went downhill fast. Any input would be great thank you.
