Struggling at 05 mg of citalopram... help me i dont want to go back

I was doing really well in my wean off process till 10 mg but as soon as i hit 05 mg its giving me trouble (anxiety and googling my symptoms and weak and crawling feelings and tingling sensation in my legs) but i really dont want to go back the road of increasing dosage. its affecting my personal life as its causing me premature ejaculation. I am also using antiallergy/ antiasthimatic medicine which is also excerbatting the situation.

What should i do? should i stay with 05 mg or increase back the dosage? @katecogs your advice especially required
