X3 symptoms and conditions

I am pregnant in my thrid trimidster. My doctor perscribed me these CEPHALEXIN MONOHYDRATE 1tab/x3 a day. BUT: I only took ONE A DAY (I was too scared to take more with baby) and found over the last 3days I have been very EMOTIONALLY ERACTIC, feeling faint and energyless during the day, with a lack of desire to eat. I have swelling from pregnancy in my feet but my arms were the limbs I noticed going numb with my hands blotchy and tingly. I felt nauscious. When I did decide to rest/ sleep I have such a terrible awake feeling and stressed that my eyes are close but I am so very awake.

Thankyou to everyone who posted their symptoms as this helped me!

am on 100mg aday x3, I notice 15 to 20 minutes after taking the pill I'm dizzy like a bad hang-over, and feel like my heart is racing for 10 - 15 minutes, anyone else experience this. Linda

I have had inflamed liver following chemo and radiation. I'm given only 100mg of Neurontin x3. I have terrible weight gain, memory loss, occassional chest pain. I worry about the effects of Neurontin on the liver. anyone know about this? I've had seizures also.
