Horribly anxious and tense feelings for 4 days now.

[diggininit]

I don't know what happened? Last week I was planting a garden, cleaning the house, listening to music and then 5 days ago I started to feel really awful, feverish, just yucky. I had been a bit anxious, but was taking Gabapentin every day and it helps, but I think this happened once before when I was taking Gabapentin for over a week (approximately 9 days to be exact). So I stopped it as my feet were swelling and I began getting this awful feverish feeling, so I attributed it to that. I started it up again and as I stated, last week, I was working outside, gardening, cleaning the house and bam 4 days ago it hit me again, so I stopped it again. Now for 4 days I am in severe pain in my back, thought I had worked too hard in the yard and have become extremely anxious again. It is overwhelming anxiety. Also at the same time I started the Gabapentin again I was also taking NAC (N-Acetylcysteine) which my psychiatrist prescribed, which is nothing more than an amino acid. So now I don't know if it was the Gabapentin or the NAC, so I stopped both. I also take Clonazepam on occasion, although not everyday, but the last 4 days, I've had to take almost 1/2 mg whereas I usually get by everyday with 1/4 mg. He also wanted me to take 1200 mg of NAC per day, but as I am very sensitive to anything at all, I only took 600 mg at night. He wanted me to take 600 mg morning and night for two weeks and then take 1800 mg a day, which would have been 3-600 mg per day. I was going to work my way up to that then this happened and now I don't know which it is, the NAC or the Gabapentin. He also wanted me to start SAMe - I know you don't hear that this often from a psychiatrist, but I think he wants to try more natural approaches. Now, I'm scared to even try the SAMe. Anxiety hit me hard 4 days ago, whereas I have trembling, feels like I have a vibrator strapped on, rapid heartbeat at times, extremely extremely exhausted. I can't remember when I felt this tired, dizzy, just really off. Unbalanced in my walking. The Gabapentin does help with the anxiety, but now twice the same thing has happened, so I really do not want to take anymore, but I really really do not want to take more Clonazepam. I'm going to see my therapist tomorrow again, but she really hasn't suggested anything that will help, although I've only seen her twice in the last 2 months. Thanks for reading.
