Is my double vision stress or cocaine?
I have had a hugh amount of stress recently including buying a house 6 weeks ago, starting up a decorating business last year and still struggling, Getting ripped off £2500 for a job last week and having my first child last week. I smoke weed most days and drink 8 cans of lager twice a week I also took quite a lot of cocaine over a couple of days for the first time in 2 years but I used to take a lot more. I had taken coke when my partner went into early labour which took 30hours. She had to stay in hospital for a week with the baby. During the week she was in hospital I juggled the business and employees, the house work (trying to get the house ready for the baby coming home) Fighting to collect the debt AND TRYING to spend every miniute I could with my partner and new baby in hospital, Then at nights I was taking a bit of cocaine. I got so stressed I was constantly had tears in my eyes for 2 days. The doctor gave me a small ammount of diazapam. Then we got the baby home, then the next morning I woke with double vision. (I had no cocain the night before) This went away after 1 hour. The hospital checked my blood pressure and my eyes and vision and put it down to stress but I didnt tell them about the cocaine. That night I drank beer and took a half gram of cocaine and the double vision came back while I was high. I have now had for 3 days, permanent double vision when both eyes are open only. When I look straight ahead my eye starts to stray on its own. Which is the cause and what is the cure?

I am 74 years old and had bypass surgery about 12 years ago. Nevertheless I am in pretty good shape. I keep very active, going a lot of gardening and having the dog take me for a long walk every day. I can even keep up with my young wife! The only medical problem that I have had for many years is high blood pressure. A couple of months ago someone recommended that I try DCPC compound hypotensive tablets from Beijing.( reserpine, chlordiazepoxide, hydrochlorothiazide, dihydralazine sulfate, triamterene) They appeared to work OK and I had no side effects. Then, a couple of days ago everything went downhill. My wife and I were at a kid’s outdoor exercise display. The sun was very hot and, after about an hour I began to feel a little weak and had to sit down. I decided to go home and felt progressively worse. My temperature was 39C, pulse about 75 and blood pressure 175/110. I also had diarrhea. I took DEXA amiodpine and atenolol and after about 2 hours my temperature and pulse were normal and pressure was 130/80. That night I had trouble sleeping. I had been working with a computer program formula and this was somehow fixed in my mind and every time I tried to think about something else my thoughts kept coming back to this stupid formula. Here in Indonesia it is always hot and I am used to the UK cold. Thus I always use a fan. For about 2 hours I got the chills and ended up covered with a thick blanket. My appetite was zero and so was my energy. The next morning I felt fine and all the symptoms except the diarrhea had disappeared. I now feel fine but really need to know what brought this on.
After a couple of days I was fine and just would like to know what brought it on. I think it was side effects from the Chinese med
