What Causes Excess Sweating,dizziness And Headache After Withdrawing Lamictal And Lexapro?

I have been on lamictal 100 mg and lexapro 20 mg for about 6 years. In March, I stopped taking them cold turkey (I will never ever do this again) anyway, I ve been really ill for th last few months and the sickness started when I stopped taking my meds. I was too afraid to tell anyone and too embarrassed and didn t want anyone to force me back on them. Anyway, I ve been getting lots of bloodtests for hormone imbalances, lymes, mono, Etc and absolutely nothing is wrong with me. It recently hit me that I may be in withdrawal. I am so sick and miserable. Sweating all the time, hot flashes, dizzy, headaches- it s like menopause, and it s constant. Anyway, I told my dr and he said to start my lexapro and lamictal again but cut the doses in half.. Well it s day 5 back on my meds and I don t feel better. I m wondering if 1) could this be withdrawal? My doctor says these meds don t usually have withdrawal symptoms, but he doesn t know that I stopped cold turkey for 3 months, and 2) if this sickness is withdrawal, wouldn t I feel better after 5 days? Should I keep waiting it out or get more tests done for other things? Thank you so much for your help, I am so desperate to feel better.
