Alprazolam and light headed

i have been taking alprazolam for many yrs for anxiety, i have gone on several anti depressants zoloft, paxil and celxa. they all gave me awful side effects. axnax has helped me the most. i am getting off of celexa , i feel light headed and shakey i have gained 40 lbs in 4 yrs. paxil was the worse to get off of. i'm 62 and have had a very hard life , i lost a son and a daughter. if i didn't try some of these meds it would have been worse for me. good luck to everyone that has to take these meds. pat
