I will first summarize my case, and then I will put my query. I had been diagnosed to have GAD and social phobia before 10 years, and I was taking Paxil 20 mg daily in the evening along with CBT. The result was excellent. The anxiety and depression went away, but with a very high level of weight gain, significant fatigue and some sexual dysfunction (low libido). Due to the side effects of the drug, I tried to withdraw it all together around two years back, and there was a relapse. Therefore, I have come back to the medication with some changes. Initially, my doctor replaced Paxil with Prozac and Wellbutrin XL, and then replaced Prozac with Zoloft. Wellbutrin had many side effects on me. Hence, I avoided it altogether. He also avoided Effexor. I am currently on Zoloft 50 mg in the evening along with Buspar 10 mg four times daily. The query now is, which of the following strategies will have few side effects like fatigue, weight gain, impotence, decreased libido, and to delay the ejaculation? A combination of 20 mg Prozac during the evening time along with Buspar 10 mg every six hours daily. A combination of 10 mg Lexapro in the evening along with Buspar 10 mg every six hours a day. A combination of 50 mg Zoloft every evening along with Buspar 10 mg every six hours daily. How would you arrange the side effects? I would like you to mention the side effects regarding impotence, libido, weight gain, fatigue, drowsiness, negative impact on the system and liver in long-term usage, control GAD, SAD and social shyness, delayed ejaculation as a positive side effect, interfere with food, other medicines and supplements etc., in a descending order. Please discuss every question in detail according to your practical experience. Best regards.
