I guess that means I love you guys. I have been dealing with issues for about 8 years now, and haven't been able to figure out what exactly is wrong. However, after reading the post on this site for a few months, I think I have a better idea. I have been diagnosed with NCS after the most enjoyable 20 minutes on the tilt table, and the resulting three days in bed miserable, the Dr. told me I had NCS, wrote down and the wrong prescription and sent me on my way with a follow up apppointment the next year... bless his heart. You can imagine my delight when I go back to see him a year later and find out he is out of the office the day he scheduled the appointment with me - and the replacement Dr. tells me I had been on the wrong meds for a year. Anyway, my journey getting to this point has been educationa if nothing else. I am going to list my symptoms and ask what you guys think?? I'm not asking for an internet diagnosis, but more or less asking for direction. I have been to two sleep studies and get no level 3 or 4 sleep and only the occasional minute of level 5 sleep... up to three minutes a night. I awake feeling completely stressed and covered in sweat... like needing to go wipe the sweat off with a towel. If I stand for more than twenty minutes or so, I start getting clammy, then my legs get sweaty, then nauseaus. If I am working in the yard, pulling weeds or anything that requires me to bend over, I get sick to my stomach. For example, I was working on my truck a few months back, getting up and down under the truck, and I got so sick, I ending up vomitting. I have no tolerance for heat, and it doesn't have to be extreme heat. Even upper 70s to 80s will make me miserable. On the other hand, I can go camping in freezing whether and I am fine. My wife calls me her personal heater. When I exert myself, I risk passing out or coming very close and I have to lay down with my feet up. If I let it go to far, I end up in bed for days feeling like I have the body aches that most people associate with the flu. So, with all of these issues, I feel pretty worthless. My 12 year old son thinks I am a lazy old man. I am not sur my wife really understands sometimes either. I think she tries, but I think it gets old for her... I know it has gotten old for me. I have always been an out going, athetic guy. I grew up rock climbing, kayaking, and doing most anything outdoors. Life has changed for the worse, and I'm not like it. I am currently taking 50 mg of Atenalol, 30 mg of Paxil, Trylipix. I typically take 2 benedryl, and 4 mgs of tizanadine to help me sleep. And, I take Prolosec daily for heartburn. I am not sure of I have POTS, or if my symptons even fit. I would like to hear what you guys think?? Thanks!! Greg Sims
