SSRI's gave me off the charts anxiety, mania and depression. I responded like I was bi-polar, but I am not bi-polar. I ultimately found out that I can't handle anything that touches the 5HT1 receptor, which most anti-depressants do. I had luck with two anti-depressants that work a bit differently and they may help you. Remeron worked fantastically for my anxiety, but it sure knocks you out and it does increase your appetite. I have also had luck with a German medication called Insidon. I'm in the US and have to order it online, so I'm not sure where you are. It's been a rather good one for me. I just take it at night instead of the twice a day recommendation. Zyprexa worked for me too, but that really can make you fat.
Yes, Lyrica (among a cocktail of 4 other drugs) did affect the way I could get things done, but I was worse off with debilitating anxiety. It's a little bit of a lottery with the side effects. They seem to be different for everyone. I would give it a shot. I take 300mg all at night - no need (for me) to take it twice a day, so the tiredness usually wears off in the morning, but I do end up sleeping about 9 hours. Again, your mileage will vary.
I have probably gained 10-20 lbs because of the Lyrica. Taking the herb Berberine with meals may help you keep the weight down or the prescription of Metformin. It helps get glucose into the cells so you don't have excess glucose in the blood.
My life was a living hell for about 6 years, but I wouldn't take it back because I have learned so much about medications, herbs, essential oils, supplements and vitamins. I'm not a health coach for people with anxiety, depression and ADD. If you want to try some natural things before you try lyrica, I have some suggestions for you
1) 200mg of Theanine in the morning or at night if it make you sleepy. This can be as powerful for some as Xanax or Klonopin
2) Tryptophan 1500mg at night. It basically does the same thing as an anti-depressent without the side effects. If that doesn't work, try 5-htp in the mornings.
3) A good B-Complex taken in the morning (Vitamin B12 needs to be methylcobalamine and there should be Folate (Vitamin B9) in there instead of the synthetic folic acid.
(You'll know if this following list of stuff works in about 2 days, so it's worth a shot)
There are several other things I can suggest, but I would give those three things a try. Feel free to reach out to me anytime if you have questions. Don't give up hope whatever you do. There is a solution for you. Believe that is what got me through feeling like a guinea pig with those 38 medications.
What country are you in?
