I ended up speaking with my doctor about getting pill form and tapering from 37.5 to the 25 mg pill and so on from there, but that day, (yesterday) I barely had any brain zaps so even though I got the prescription filled, I decided not to take them. I woke up today feeling decent again (compared to the last couple of days) and was even able to handle work for a while. I am exactly one week without effexor. I hope it doesn't get worse, but I will re-evaluate at that time if it does. Thank you all for your advice and support.
