This thread might get moved to the Medications and Treatment section. Anyway, I am currently taking Klonopin and Zoloft. The Zoloft is new, so I'm not sure how it will work out yet. I have been on it about two weeks and have had some very mild headachiness and seem a little sleepier than usual, and my period came about a week early, but none of this is anything to write home about. Zoloft is a selective serotonin reuptake inhibitor (SSRI) and those take about 4-6 weeks to kick in, so I would not expect to see real results right away. In the long term, if it works, it should help take the edge off of anxiety and depression symptoms by raising serotonin levels in the body. Serotonin is a neurotransmitter that affects well-being and mood; too little of it is thought to be related to anxiety and/or depression in some people.
Klonopin is the same type of medication as Xanax, a benzodiazepine. The difference is that Klonopin lasts for a much longer time, so it is more often prescribed for people who have ongoing anxiety, and Xanax works quickly and for a short period of time, so it is prescribed for panic attacks. I have found that Klonopin helps calm me down a lot for about 24 hours, but it can cause dependence and I had some unpleasant withdrawal symptoms when I stopped taking it previously. So, I try not to take it every day. I have not noticed any immediate side effects with Klonopin, apart from feeling very mellow and chill, but when I took it for a longer period of time (every day for a few months), it made me very tired and I had a hard time thinking clearly.
Hope this helps!
