Orgasm problem symptoms and conditions

I took lexapro for anxiety and mild depression for 3 months, but after experiencing anorgasm, (the inability to reach orgasm) I talked to my doctor and we decided to try Wellbutrin. I have been on it for a week, and I am experiencing the jittery, boxed up nervousness. In addition today I dry heaved all day.....I almost feel like I did when I took adderall for ADHD in College (got off of that b/c it made me a zombie-ish b*tch) And last night I cried for 2 hours without really knowing why. So, I don't know if maybe this med is not good for me, and if I should notice some relief by now....lexapro was great for the mood--always happy, easy going and a bit nonchalant, but I gained 10 pounds in 3 months (started at 115 so 10 lbs is a lot for a person as small as I am) and the orgasm problem was not good as I am 27 and newly married....wondering if there is anyone out there that switched from lexapro to wellbutrin and if their symptoms subsided after a couple of weeks......
