You are not alone! I have been on Lexapro for years and it just seemed to "stop" working. I started taking Prozac in April and still felt all of the depression symtoms well into July. I quit Prozac cold turkey (against the better judgement of my therapist) and felt pretty good (side effect-wise). Here it is almost two months later and I am feeling that "head-buzzing"-foggy feeling now. What's that about? I DO NOT want to take any of that stuff again. I am 45 yrs old an am sure a lot of this is menapause/hormone related but like you I don't know which doctor to take this to. My Ob/Gyn is the one who put me on prozac and also told me to try the over-the-counter daily vitamins for women-estroven, etc. But it's not enough. I want a more solid diagnosis and a solution. Who in the world are we supposed to ask?????
Hormone imbalances are a common physiological cause of anxiety and depression, whether it be sexual hormones, sugar imbalances and insulin, or thyroid hormones. If you've been off Prozac for three months and are just getting symptoms now, and it's just digestive and anxiety problems as opposed to things like disorientation, dizziness, brain zaps, or emotional problems you never had before taking the Prozac, then it's probably your original problem resurfacing. Prozac does have a delayed withdrawal possibility because it stays in the body much longer than the others, but this is thought to be a good thing, allowing the body to slowly adjust to the lack of the drug. This doesn't mean it can't be a withdrawal, but it's not the likeliest scenario unless there's more going on than your description. Remember, medication doesn't cure, it just mitigates symptoms. If you haven't found a way to deal with the problem it will most likely still be there when you quit a med.
Like cj29, I sympathize with your distress. I didn't have any problem discontinuing Prozac, but was taking a small dose of clonazapam at the same time, which may have helped.
It is darn hard to figure out if anxiety and digestive issues are caused by the anxiety disorder or withdrawal from Prozac. My money is on the disorder. Can't believe hormone issues are the culprit.
Always good to rule out physical sources of discomfort. If all is within normal ranges, it is time to talk to a therapist. Best luck.
I am sorry you are going through this right now. When I stopped Zoloft, I had some side effects as I tapered but they slowly went away. Are you in counseling right now? For me, sometimes it can be hard to tell what is withdrawal and what is your anxiety.
