... experienced the usual withdrawal symptoms, vertigo, nausea, electric zaps, etc. Since I felt that I needed more of the med in the daytime to keep the withdrawal symptoms in check, I switched to taking the medication during the day. Now I cannot keep my eyes open and have found myself adding caffiene to my diet (which I have been off of for about 2 years and as we all know its NOT great for anxiety)... so my question is, do I continue to take Effexor during the day and deal with the sleepiness or take it at night and deal with the withdrawals during the day?
