Were you weaning off the time release version or the regular one? 37.5 is too large a drop. If it doesn't come in a smaller dose, switch to the regular non-time release version. I know they make a 25 mg tablet. Go down not more than 10% a month, which would be 3.75 mg. for your first drop. You would then be taking 33.8 mg. Then go down 10% of 33.8 mg. If you don't have a mg. scale, a compounding pharmacist could show you about how much to break off. The drop to nothing is the hardest. I know because I came off my final dose of Pristiq too quickly. (Pristiq doesn't come in a non-time release form.) The withdrawal wasn't terrible because I was exercising and doing yoga about 2 hours a day, but it was bad enough. I was getting painful mood swings and a weird feeling of disorientation, like when you have a fever. It lasted for about 2 months. The withdrawal symptoms you're getting could be protracted. If you decide to stick it out, keep an eye on your blood pressure, eat high-quality food and try to walk a half hour a day. (The exercise helped me tremendously.) Withdrawing too quickly stresses your body and mind. Try to be kind to yourself.
